Module: conmax_module

G2a

G2a: verified

Derivatives / callbacks: not applicable

Linear-programming entry point; constrained minimax routines are separate. Dedicated G2a driver checks three scaled free-variable LPs maximizing -y under x+y>=a, x-y<=b. Known intersections, primal feasibility, solver-reported objective and a nonnegative analytical dual certificate are checked. Infeasibility, unboundedness and general LP robustness are not tested.
