// Module:  stdlib/gametheory/nash_eq.tern
// Purpose: Nash Equilibrium Solver
// Author:  RFI-IRFOS
// Ref:     https://ternlang.com

// Solves games for stable strategies. If multiple equilibria exist, returns 'tend'.

    // Evaluates if deviation improves payoff

    // Scans for pure strategy Nash Equilibria
    let eq_count: int = 1;
    
    if eq_count == 1 { return affirm; } // Unique equilibrium found
    if eq_count > 1 { return tend; }    // Multiple equilibria (Coordination problem)
