Enumeration Type Documentation

SCIP_SolOrigin

enum SCIP_SolOrigin

origin of solution: where to retrieve uncached elements

Enumerator
SCIP_SOLORIGIN_ORIGINAL	solution describes original variables; non-cached elements are zero
SCIP_SOLORIGIN_ZERO	all non-cached elements in solution are equal to zero
SCIP_SOLORIGIN_LPSOL	all non-cached elements in solution are equal to current LP solution
SCIP_SOLORIGIN_NLPSOL	all non-cached elements in solution are equal to current NLP solution
SCIP_SOLORIGIN_RELAXSOL	all non-cached elements in solution are equal to current relaxation solution
SCIP_SOLORIGIN_PSEUDOSOL	all non-cached elements in solution are equal to current pseudo solution
SCIP_SOLORIGIN_PARTIAL	solution describes original solution; all non-cached elements in solution are treated as being an arbitrary value in the variable's bounds
SCIP_SOLORIGIN_UNKNOWN	all non-cached elements in solution are unknown; they have to be treated as being an arbitrary value in the variable's bounds

Definition at line 31 of file type_sol.h.

SCIP_SolType

enum SCIP_SolType

type of solution: heuristic or (LP) relaxation solution, or unspecified origin

Enumerator
SCIP_SOLTYPE_UNKNOWN	type of solution unspecified (the default)
SCIP_SOLTYPE_HEUR	solution was found by a heuristic
SCIP_SOLTYPE_RELAX	solution was found by a relaxation
SCIP_SOLTYPE_LPRELAX	solution was found by the LP relaxation
SCIP_SOLTYPE_STRONGBRANCH	solution was found during strong branching
SCIP_SOLTYPE_PSEUDO	solution originates from a pseudo solution
