Detailed Description

Struct that holds the parameters of the LP solver.

This structure contains various parameters that control the behavior of the LP solver, including algorithm selection, cut generation, heuristics, and output control.

Most parameters have reasonable defaults and don't need to be modified for basic use cases. Advanced users can tune these parameters to improve performance for specific problem types.
