Provides: - Unified API across solvers (OR-Tools, Gurobi, CPLEX) - Capability detection - Automatic linearization when needed - Type-safe solution mapping

Parameters:: capability (LXSolverCapability)

__init__(capability)[source]¶

Initialize solver interface.

Parameters:: capability (LXSolverCapability) – Solver capability description

Methods

`__init__`(capability)	Initialize solver interface.
`build_model`(model)	Build solver-specific model from LumiX model.
`get_solver_model`()	Get underlying solver model for advanced usage.
`solve`(model[, time_limit, gap_tolerance])	Solve the optimization model.
