## Abstract

This round establishes a mathematical state machine arena shared by both the $P=NP$ and $P\neq NP$ hypotheses. The core approach is neither to pre-select an existing algorithm nor to presume that $NP$ problems require item-by-item search. Instead, it isolates the existential quantifier in the polynomial-time verifier,

$$
\exists w
$$

asking whether it can be collapsed by a unified, finite, exact, and polynomial-resource-bounded mathematical state machine.

Given a polynomial-time verifier

$$
V(x,w)\in\{0,1\},
$$

we define the existential aggregation function

$$
\operatorname{EX}_V(x)
=
\bigvee_{w\in\{0,1\}^{p(|x|)}}V(x,w).
$$

This round thus rewrites the traditional $P/NP$ problem as: Does there exist a unified family of mathematical state machines that exactly computes $\operatorname{EX}_V(x)$ within polynomial description length, construction time, state resources, precision, transition time, and decoding time?

The $P=NP$ side argues: There exists some unknown global mathematical compression structure such that candidate witnesses do not need to be expanded item by item. The $P\neq NP$ side argues: Any exact and unified existential quantifier compressor must inevitably exhibit superpolynomial growth in at least one necessary resource.

This round has not yet yielded a proof for either $P=NP$ or $P\neq NP$; its achievement is concentrating the debate of both sides onto a common object: the **existential quantifier compressor** $\mathcal C_{\exists}$, and establishing a reusable framework for attack, defense, and scrutiny in subsequent rounds.

# I. Research Objectives

This research originally used $P/NP$ as the foundation for the dynamics of agent cognitive processes, distinguishing between search, generation, computation, verification, memory, and knowledge condensation. The mathematical construct-state machine intermediate layer further supplements this: after an agent gains insight, how does that insight become a repeatedly executable capability through formalization, mathematical construction, and substrate implementation.

This round officially enters the traditional $P/NP$ proposition, but without immediately choosing a single path. The research methodology shifts to:

$$
H_{=}:P=NP
$$

and

$$
H_{\neq}:P\neq NP
$$

simultaneously establishing the strongest versions of both, and having them attack each other under the same model, the same resource accounting rules, and the same standards of correctness.

This method is called:

$$
\boxed{\text{Dual-Hypothesis Rehearsal Method}}
$$

Its goal is not to let both sides remain in philosophical stances, but to force them to respectively propose:

- What the affirmative side needs to construct;
- What the opposing side needs to rule out;
- Which costs cannot be omitted;
- Which arguments only apply to restricted models;
- Which barriers would invalidate candidate proofs.

---

# II. Reconfiguration of the Old Series

The original series features two important distinctions.

First, mathematical and computational problems can be studied separately at the static formal layer and the dynamic cognitive layer. Second, whether an algorithm exists and whether an agent can find that algorithm are two different problems.

In traditional $P/NP$, these two layers must first be rearranged.

## 2.1 Object Layer

The object layer problem is:

$$
\exists A,
\quad
\text{Can } A \text{ decide SAT in polynomial time?}
$$

Here, the only concern is the asymptotic resource cost of a completed algorithm for any arbitrary input.

## 2.2 Meta Layer

The meta layer problem is:

$$
\text{How do researchers discover, construct, or prove the non-existence of this } A?
$$

The fact that an algorithm is difficult to find is insufficient to deduce its non-existence. Even if a fixed algorithm is extremely difficult to discover in human history, as long as it runs in polynomial time for all inputs once completed, it can still prove $P=NP$.

Therefore:

$$
\text{Epistemologically unobtainable}
\not\Rightarrow
\text{Ontologically non-existent}.
$$

However, the cognitive dynamics of the original series can still be used to study proof generation, representation discovery, and algorithm construction, though they cannot directly replace traditional complexity lower bounds.

# III. Common Arena: Unified Mathematical State Machine

Fix a polynomial-time verifier:

$$
V(x,w)\in\{0,1\},
$$

where $x$ is the problem instance, $w$ is the candidate witness, and:

$$
|w|\leq p(|x|)
$$

holds for some polynomial $p$.

The corresponding language is:

$$
L_V
=
\left\{
 x\mid\exists w,
 V(x,w)=1
\right\}.
$$

The true difference in the traditional $NP$ verification formulation lies in the existential quantifier. Thus, we define:

$$
\operatorname{EX}_V(x)
=
\bigvee_{w\in\{0,1\}^{p(|x|)}}V(x,w).
$$

Then:

$$
x\in L_V
\iff
\operatorname{EX}_V(x)=1.
$$

A candidate deterministic solver is represented as:

$$
\mathfrak M
=
(Q,\operatorname{Enc},\delta,\operatorname{Out}),
$$

where:

$$
q_0=\operatorname{Enc}(x),
$$

$$
q_{t+1}=\delta(q_t),
$$

and after some termination time $T$, it satisfies:

$$
\operatorname{Out}(q_T)
=
\operatorname{EX}_V(x).
$$

This mathematical state machine is not limited to traditional code. It can be expressed by any of the following finite forms:

- Turing machines or RAM programs;
- Boolean circuits;
- Matrix or tensor evolutions;
- Algebraic functions;
- Graph structures;
- Finite state machines;
- Knowledge compilation representations;
- Other finite mathematical structures that can be constructed and simulated by a deterministic machine within polynomial resources.

This common arena precludes two types of equivocation:

1. The $P=NP$ side may not hide exponential costs in precomputation, infinite precision, or ungeneratable structures;
2. The $P\neq NP$ side may not merely prove the failure of a specific class of searchers, decision trees, or representation systems.

---

# IV. Formal Hypotheses of Both Sides

## 4.1 The $P=NP$ Hypothesis

$$
H_{=}
:
\exists\mathfrak M,\exists k,
\quad
T_{\mathfrak M}(x)
\leq
|x|^k
$$

holds for all inputs $x$, and $\mathfrak M$ exactly computes $\operatorname{EX}_V(x)$.

This side needs to demonstrate a unified, polynomial-resource-bounded existential quantifier compressor.

## 4.2 The $P\neq NP$ Hypothesis

$$
H_{\neq}
:
\forall\mathfrak M,
\forall k,
\exists x,
\quad
T_{\mathfrak M}(x)>|x|^k.
$$

Its quantifier order is:

$$
\boxed{
\forall\mathfrak M
\ \forall k
\ \exists x
}
$$

The opposing side must rule out all possible deterministic polynomial-time implementations, not just currently known algorithms.

---

# V. Video Inspiration: Algorithms Cannot Be Presumed as Search

The Rock-Paper-Scissors case shows that finite rules:

$$
1\mapsto3,
\qquad
2\mapsto1,
\qquad
3\mapsto2
$$

can be implemented by functions, modular arithmetic, polynomials, or state transitions.

Therefore:

$$
\text{Conditional Branching}
\rightarrow
\text{Mathematical Function}
\rightarrow
\text{State Machine Behavior}.
$$

This illustrates a crucial limitation:

> Proving that item-by-item search requires exponential time is not equivalent to proving that all possible algorithms require exponential time.

An unknown algorithm might not perform item-by-item search at all, but instead use some global mathematical structure to compute the answer directly.

Thus, this round refocuses the problem to:

$$
\boxed{
\text{Can } \operatorname{EX}_V \text{ be folded into a polynomially executable construct, just like finite rules?}
}
$$

---

# VI. Strongest Opening for the $P=NP$ Side

The $P=NP$ side proposes: There exists a currently unknown compression operator

$$
\mathcal C:
(V,x)
\mapsto
R_{V,x},
$$

such that:

$$
|R_{V,x}|
\leq
\operatorname{poly}(|x|),
$$

$$
T_{\mathcal C}(V,x)
\leq
\operatorname{poly}(|x|),
$$

and:

$$
\operatorname{Eval}(R_{V,x})
=
\bigvee_wV(x,w)
$$

can also be completed in polynomial time.

This structure could be:

- A global algebraic invariant;
- An unknown normal form;
- A structural quantity capable of directly measuring the existence of a solution;
- A compressed representation that automatically eliminates invalid branches;
- A transformer that does not require explicitly generating the candidate solution space.

The core stance of this side is not "enumerating $2^m$ witnesses faster," but rather:

$$
\boxed{
\text{The candidate space does not need to be represented as } 2^m \text{ mutually independent objects.}
}
$$

Therefore, the candidate proof route is:

$$
\text{Existential Quantifier}
\rightarrow
\text{Global Mathematical Compression}
\rightarrow
\text{Polynomial State Evolution}.
$$

---

# VII. Strongest Opening for the $P\neq NP$ Side

The $P\neq NP$ side cannot merely use the number of candidates as a lower bound, because massive implicit structures do not necessarily require item-by-item expansion.

A stronger stance is:

> Any unified finite mathematical state machine that exactly computes the general $NP$ existential quantifier must exhibit superpolynomial growth in at least one necessary resource.

Define the complete resource vector:

$$
\mathbf R_{\mathfrak M}(n)
=
\left(
L_{\mathrm{desc}},
T_{\mathrm{construct}},
M_{\mathrm{state}},
P_{\mathrm{precision}},
T_{\mathrm{transition}},
T_{\mathrm{decode}}
\right).
$$

where:

- $L_{\mathrm{desc}}$: Structural description length;
- $T_{\mathrm{construct}}$: Time to construct the structure based on the input or input length;
- $M_{\mathrm{state}}$: Usable state and memory resources;
- $P_{\mathrm{precision}}$: Precision required for coefficients, amplitudes, or continuous states;
- $T_{\mathrm{transition}}$: State evolution time;
- $T_{\mathrm{decode}}$: Time to read the answer from the final state.

The opposing side's ideal goal is:

$$
\forall\mathfrak M,
\quad
\text{if } \mathfrak M \text{ exactly decides SAT, then}
$$

$$
\max\mathbf R_{\mathfrak M}(n)
\notin
\operatorname{poly}(n).
$$

That is, complexity may shift to different locations, but it cannot simultaneously vanish from all necessary locations.

# VIII. First Thought Experiment: Variable-by-Variable Elimination

Let:

$$
\varphi(x_1,\ldots,x_m)
$$

be a SAT instance.

For a single variable:

$$
\exists x_1\,\varphi
\equiv
\varphi[x_1=0]
\lor
\varphi[x_1=1].
$$

Let:

$$
R_0=\varphi,
$$

and sequentially define:

$$
R_{i+1}
=
\operatorname{Norm}
\left(
R_i[x_{i+1}=0]
\lor
R_i[x_{i+1}=1]
\right).
$$

After all variables are eliminated:

$$
R_m\in\{0,1\},
$$

and:

$$
R_m=1
\iff
\varphi \text{ is satisfiable}.
$$

The real point of contention is:

$$
\operatorname{Norm}.
$$

## 8.1 $P=NP$ Side Rehearsal

There exists an exact normalization operator $\operatorname{Norm}_{=}$ such that:

$$
|R_i|
\leq
\operatorname{poly}(|\varphi|)
$$

and:

$$
T_{\operatorname{Norm}_{=}}(R_i)
\leq
\operatorname{poly}(|\varphi|)
$$

holds for all intermediate steps.

If the number of variables also has only a polynomial relationship with the input length, then the complete elimination remains in polynomial time.

## 8.2 $P\neq NP$ Side Rehearsal

For any candidate exact normalization $\operatorname{Norm}$, there always exists a family of formulas $\{\varphi_n\}$ such that at least one type of explosion occurs at some step:

$$
|R_i|
\geq
2^{\Omega(n)},
$$

or:

$$
T_{\operatorname{Norm}}(R_i)
\geq
2^{\Omega(n)},
$$

or:

$$
P_{\mathrm{precision}}
\geq
2^{\Omega(n)}.
$$

However, it must be noted: proving that a specific class of variable-by-variable elimination methods explodes is still insufficient to prove $P\neq NP$, because completely different algorithms might exist.

Therefore, this thought experiment is merely a local model, used to search for potential cross-representational invariants.

# IX. Round 1 Mutual Attacks

## 9.1 $P\neq NP$ Side Attacks $P=NP$

### Attack A: Non-uniformity Smuggling

If a special structure $C_n$ is prepared in advance for each input length $n$, but there is no polynomial-time generator:

$$
G(1^n)=\langle C_n\rangle,
$$

then the construction cost might be hidden outside the model.

Thus, it is required that:

$$
T_G(n)
\in
\operatorname{poly}(n).
$$

### Attack B: Infinite Precision Smuggling

A short real constant might encode exponential or even uncomputable information within its infinite bits. Therefore, coefficient bit-length, precision maintenance, and read costs must be accounted for.

### Attack C: Preprocessing Cost Smuggling

If:

$$
T_{\mathrm{Eval}}
\in
\operatorname{poly}(n),
$$

but:

$$
T_{\mathrm{construct}}
\in
2^{\Omega(n)},
$$

then the search is merely shifted to before runtime.

### Attack D: Approximation Masquerading as Exactness

Success on most instances, specific distributions, or with high probability is not equivalent to the traditional worst-case exact $P=NP$.

## 9.2 $P=NP$ Side Attacks $P\neq NP$

### Attack A: Presuming Search is Required

If the opposing side assumes a priori that the algorithm must check witnesses one by one, they are embedding the conclusion into the premise.

### Attack B: Treating Representation as Ontology

An explosion in CNF, DNF, decision trees, BDDs, or a certain class of algebraic representations does not mean that all possible mathematical representations will explode.

### Attack C: Misusing Input Candidate Information Content

SAT ultimately only outputs:

$$
0
\quad\text{or}\quad
1.
$$

One cannot deduce that the output itself requires exponential information solely from the number of candidate witnesses.

### Attack D: Counting Discovery Time as Algorithm Time

The human discovery history of a fixed algorithm does not belong to its traditional runtime complexity for an input.

### Attack E: Extrapolating from Restricted Models

A lower bound for a specific decision tree, circuit depth, proof system, or algebraic model cannot be automatically elevated to a lower bound for all deterministic polynomial-time machines.

# X. Three Major Proof Barriers as Scrutinizers

Every candidate proof must pass through three scrutinizers.

## 10.1 Relativization Scrutiny

If an argument remains valid for any oracle, it must be checked whether it falls into the relativization barrier. This is because there exist oracle worlds that respectively satisfy:

$$
P^A=NP^A
$$

and:

$$
P^B\neq NP^B.
$$

## 10.2 Natural Proofs Scrutiny

If a candidate lower bound method possesses both largeness and constructivity, it must be checked whether it falls into the natural proofs barrier.

## 10.3 Algebrization Scrutiny

Even if the method incorporates arithmetization or low-degree polynomial extensions, it must be checked whether it still falls within the scope covered by algebrization techniques.

These three scrutinizers do not prove that the problem is unsolvable; rather, they are used to prematurely eliminate types of methods known to be insufficient.

# XI. Tentative Results of Round 1

This round did not yield:

$$
P=NP
$$

or:

$$
P\neq NP.
$$

What this round yielded is a common core:

$$
\boxed{
\text{The mathematical state machine version of } P/NP\text{, the core of which is whether the existential quantifier can be unifiedly, exactly, and polynomially collapsed.}
}
$$

The $P=NP$ side needs to construct:

$$
\boxed{
\text{A polynomial existential quantifier compressor}
}
$$

The $P\neq NP$ side needs to prove:

$$
\boxed{
\text{The non-existence of a polynomial existential quantifier compressor across representations and algorithmic forms.}
}
$$

The common research object is tentatively set as:

$$
\mathcal C_{\exists}.
$$

Its specification is:

$$
\mathcal C_{\exists}:
V(x,w)
\mapsto
\exists w\,V(x,w),
$$

and it is subject to complete resource ledger scrutiny.

# XII. Tentative Conjecture of Round 1

> **Existential Quantifier State Collapse Conjecture**
>
> For any polynomial-time verifier $V(x,w)$, does there exist a unified finite mathematical state machine that, within polynomial description length, construction time, space, precision, state evolution, and decoding time, exactly computes
>
> $$
> \bigvee_wV(x,w)?
> $$

The affirmative side answers:

$$
\text{It exists, therefore } P=NP.
$$

The opposing side answers:

$$
\text{It does not exist, therefore } P\neq NP.
$$

This conjecture is currently a state-machine restatement of the original problem, not a completed breakthrough; however, it transforms the abstract solving-verifying discrepancy into a common research object that can be subjected to round-by-round thought experiments, constructions, attacks, and formalizations.

---

# XIII. Entry to the Next Round

Round 2 will investigate:

$$
\boxed{
\text{What properties might serve as cross-representational invariants that do not vanish under existential quantifier collapse?}
}
$$

Initial candidates include:

1. State distinguishability;
2. Constraint interaction order;
3. Post-projection representational growth;
4. Proof width or elimination width;
5. Historical dependence and path incompressibility;
6. Uniform generation cost;
7. Minimum precision and memory requirements for exactness.

Round 2 similarly requires:

- The $P=NP$ side to propose how to bypass candidate invariants;
- The $P\neq NP$ side to prove why candidate quantities hold across representations;
- Both sides to mutually construct counterexamples;
- Finally, passing relativization, natural proofs, and algebrization scrutiny.
