[FEAT-AGENT][Added Graph of Thoughts agent]

[IlumCI]

Description:
This PR introduces the GoT (Graph-of-Thought) Agent, a sophisticated reasoning system
that models reasoning as a labeled directed graph with probabilistic semantics. Unlike
linear chain-of-thought or tree-based approaches, GoT enables complex reasoning structures
with cycles, merges, and refinement operations through graph neural networks and spectral
analysis.

Issue: N/A (New Feature)

Dependencies:

• numpy (for numerical computations and graph operations)
• Standard library: dataclasses, typing, enum, uuid, collections

================================================================================
WHAT IS THE GOT AGENT?

The GoT Agent is a graph-based reasoning system that performs:

1. GRAPH CONSTRUCTION: Builds thought graphs with nodes representing reasoning steps
2. NEURAL MESSAGE PASSING: Uses GNNs to propagate information through the graph
3. GRAPH OPERATIONS: Supports EXPAND, MERGE, REFINE, and ADD_EDGE operations
4. SPECTRAL ANALYSIS: Analyzes graph structure using Laplacian eigenvalues
5. QUANTUM SUPERPOSITION: Implements quantum-inspired graph measurement
6. MDP-BASED CONTROL: Uses Markov Decision Process for optimal graph construction

Unlike tree-based reasoning (ToT) or linear chains (CoT), GoT allows:

• Cyclic reasoning structures (feedback loops)
• Node merging (combining similar thoughts)
• Node refinement (improving existing thoughts)
• Complex multi-hop reasoning paths

================================================================================
HOW IT REVOLUTIONIZES REASONING

FLEXIBLE REASONING STRUCTURES:
Traditional reasoning follows linear or tree structures. GoT enables arbitrary graph
topologies, allowing:

• Feedback loops where later thoughts refine earlier ones
• Parallel reasoning paths that merge at key points
• Multi-hop reasoning where intermediate steps connect distant concepts
• Cyclic refinement where thoughts improve iteratively

Example: In mathematical problem solving, GoT can represent:

• Problem node → Hypothesis nodes (multiple approaches)
• Hypothesis nodes → Subproblem nodes (breakdown)
• Subproblem nodes → Intermediate results
• Intermediate results → Merge node (combining insights)
• Merge node → Refined solution → Final answer

This structure captures the non-linear nature of human reasoning better than trees or chains.

ADAPTIVE GRAPH CONSTRUCTION:
The agent uses an MDP-based controller to decide which operations to apply:

• Information gain: Selects nodes with highest information gain I(v; Y | G, X)
• Centrality measures: Uses degree, betweenness, closeness, eigenvector centrality
• Value estimation: MDP value functions guide optimal node selection
• Multi-objective optimization: Balances exploration vs exploitation

Example: When solving a complex problem, the controller:

1. Identifies leaf nodes (unexplored thoughts)
2. Computes information gain for each potential expansion
3. Considers graph centrality (important nodes get priority)
4. Selects optimal node using composite scoring
5. Applies EXPAND, MERGE, or REFINE based on graph state

NEURAL GRAPH REPRESENTATION:
GoT uses Graph Neural Networks to encode graph structure:

• GCN layers: H^(k+1) = σ(Ã H^(k) W^(k)) with normalized adjacency
• GAT layers: Attention-based message passing with multi-head attention
• Graph Transformers: Full self-attention over graph nodes
• Graph-level readout: Aggregates node embeddings to graph embedding

This enables:

• Similarity detection between reasoning graphs
• Transfer learning across problem domains
• Graph-based reasoning quality assessment
• Semantic understanding of reasoning structure

================================================================================
MATHEMATICAL FOUNDATION

CORE PROBABILISTIC MODEL:
The GoT framework models reasoning as:

p_θ(y, G | x) = p_θ(G | x) · p_θ(y | G, x)

Where:

• x ∈ X: input problem
• y ∈ Y: final answer
• G = (V, E, τ, ℓ, σ): thought graph
  • V = {v₁, ..., vₙ}: vertices (thought units)
  • E ⊆ V × V × R: directed edges with relations
  • τ: V → T: node type mapping
  • ℓ: V → S*: node labels (text)
  • σ: V → R^d: node embeddings

FACTORIZATION OVER GRAPH:
The graph probability factorizes in topological order:

p_θ(G | x) = ∏_{v_i ∈ V} p_θ(ℓ(v_i), Pa(v_i), τ(v_i) | x, G_{<i})

Where Pa(v_i) = {v_j : (v_j, v_i, r) ∈ E} are parent nodes.

GRAPH NEURAL NETWORK MESSAGE PASSING:
Node embeddings are updated through message passing:

H^(k+1) = σ(A H^(k) W^(k) + B H^(k))

Where:

• H^(k) ∈ R^{n×d}: node embeddings at layer k
• A ∈ R^{n×n}: adjacency matrix
• W^(k) ∈ R^{d×d}: learnable weights
• B ∈ R^{d×d}: residual connection
• σ: nonlinearity (ReLU, GELU)

Graph-level readout:
h_G = READOUT({h_v : v ∈ V})

Methods: Mean pooling, Max pooling, Sum pooling, Attention pooling.

SPECTRAL GRAPH THEORY:
Graph Laplacian analysis:

L = D - A (unnormalized)
L_norm = D^{-1/2} L D^{-1/2} (normalized)

Eigenvalue decomposition:
L = Φ Λ Φ^T

Where:

• Λ = diag(λ₁, ..., λₙ): eigenvalues (spectrum)
• Φ: eigenvectors (graph Fourier basis)

Graph Fourier Transform:
F(λ) = Σ_{v} h_v · φ_v(λ)

QUANTUM GRAPH SUPERPOSITION:
Quantum state representation:

|ψ_G⟩ = Σ_{G ∈ G} α_G |G⟩ ⊗ |y_G⟩

Where:

• α_G = √(p_θ(G | x)): amplitude
• |G⟩: graph basis state
• |y_G⟩: answer state

Measurement probability:
P(y | x) = |⟨y | ψ_G⟩|² = |Σ_{G: y_G=y} α_G|²

MARKOV DECISION PROCESS:
Graph construction as MDP:

• State: S_t = G_t (current graph)
• Action: a_t ∈ {EXPAND, MERGE, REFINE, ADD_EDGE, STOP}
• Transition: S_{t+1} = f_θ(S_t, a_t)
• Reward: R(S_T) = quality(y | G_T, x)
• Policy: π_θ(a_t | S_t, x) = softmax(Controller_θ(Enc_φ(S_t, x)))

Value function:
V^π(S_t) = E_π[Σ_{k=t}^T γ^{k-t} R(S_k) | S_t]

Q-function:
Q^π(S_t, a_t) = E_π[Σ_{k=t}^T γ^{k-t} R(S_k) | S_t, a_t]

INFORMATION-THEORETIC PROPERTIES:
Graph entropy:
H(G | X) = -Σ_{G} p_θ(G | x) log p_θ(G | x)

Mutual information:
I(G; Y | X) = H(Y | X) - H(Y | G, X)

Node information gain:
I(v; Y | G, X) = H(Y | G, X) - H(Y | G ∪ {v}, X)

Graph complexity:
C(G) = |V| log |V| + |E| log |E| + Σ_{v} |ℓ(v)|

STATISTICAL MECHANICS:
Energy function:
E(G, x) = -log p_θ(G | x) = -Σ_{v_i} log p_θ(v_i | Pa(v_i), x)

Boltzmann distribution:
p_θ(G | x) = (1/Z(x)) exp(-E(G, x) / T)

Partition function:
Z(x) = Σ_{G ∈ G} exp(-E(G, x) / T)

Free energy:
F(x) = -T log Z(x)

GRAPH TOPOLOGY:
Centrality measures:

• Degree: C_deg(v) = deg(v) / (|V| - 1)
• Betweenness: C_bet(v) = Σ_{i≠j≠v} σ_{ij}(v) / σ_{ij}
• Closeness: C_clo(v) = (|V| - 1) / Σ_{u≠v} d(v, u)
• Eigenvector: C_eig(v) = (1/λ) Σ_{u} A_{vu} C_eig(u)

Clustering coefficient:
C(v) = (2e_v) / (k_v(k_v - 1))

Where e_v = edges among neighbors, k_v = degree of v.

================================================================================
CORE IMPLEMENTATION DETAILS

GRAPH CONSTRUCTION PROCESS:

1. Initialize root node with problem statement
2. Iterative graph expansion:
   • Controller selects node using information gain + centrality
   • Controller selects operation (EXPAND/MERGE/REFINE/STOP)
   • Apply operation to modify graph
   • Update node embeddings via GNN
   • Evaluate new/modified nodes
3. Graph encoding for final representation
4. Answer synthesis from graph structure

score(v) = w₁·I(v; Y | G, X) + w₂·C(v) + w₃·V^π(v)

Where:

• I(v; Y | G, X): information gain
• C(v): centrality (degree + closeness)
• V^π(v): MDP value estimate

Implementation:

def select_node(graph, problem):
    candidates = [v for v in graph.nodes if is_leaf(v)]
    
    scores = []
    for v in candidates:
        uncertainty = 1.0 - v.score
        degree_cent = degree_centrality(graph, v)
        closeness_cent = closeness_centrality(graph, v)
        value_est = mdp_value_estimate([v.score])
        
        composite = 0.4 * uncertainty + \
                   0.3 * (degree_cent + closeness_cent) + \
                   0.3 * value_est

• Accepts model_name, agent_name, llm, agent parameters
• Uses AgentLLMAdapter for LLM integration
• Follows same initialization pattern

================================================================================
PERFORMANCE IMPACT

The GoT Agent adds new functionality without impacting existing code performance.

Computational complexity:

• Graph construction: O(|V| · (expand_cost + eval_cost))
• GNN forward pass: O(|E| · d²) per layer
• Topological sort: O(|V| + |E|)
• Spectral analysis: O(|V|³) for full eigendecomposition
• With MDP search (T steps): O(T · (|V| · expand_cost + |E| · d²))

Optimizations:

• Efficient graph data structures
• Vectorized GNN operations
• Topological caching
• Sparse matrix operations where applicable

Memory complexity:

• Graph storage: O(|V| · d + |E|)
• GNN activations: O(|V| · d · num_layers)
