Type Alias ActiveProfile 

pub type ActiveProfile = HighsProfile;

The solver profile type of the compile-time-selected active backend.

Resolved under the same mutually-exclusive backend contract as ActiveSolver (enabling both backends is a compile error): this is ClpProfile under --features clp, otherwise HighsProfile under the default highs feature. When neither feature is enabled, this alias is not defined. It is the same type as <ActiveSolver as SolverInterface>::Profile.

Fields

primal_feasibility_tolerance: f64

Primal feasibility tolerance.

dual_feasibility_tolerance: f64

Dual feasibility tolerance.

simplex_iteration_limit: u32

Per-attempt simplex iteration cap. DEFAULT_PROFILE_HEURISTIC_SENTINEL (0) selects the historical heuristic num_cols * 50 max 100_000.

ipm_iteration_limit: u32

Per-attempt IPM iteration cap. DEFAULT_PROFILE_IPM_UNBOUNDED_SENTINEL (0) means unbounded (i32::MAX).

simplex_dual_edge_weight_strategy: i32

HiGHS simplex_dual_edge_weight_strategy (-1=Choose, 0=Dantzig, 1=Devex, 2=SteepestEdge).

simplex_scale_strategy: i32

HiGHS simplex_scale_strategy (0=Off, 1=Choose, 2=Curtis–Reid, 4=Equilibration). The cobre prescaler already normalizes matrix entries, so the default is 0 (off).

simplex_price_strategy: i32

HiGHS simplex_price_strategy (0=Col, 1=Row, 2=RowHyperSparse, 3=RowSparse).
