CPXXgetnodeleftcnt and CPXgetnodeleftcnt

The routine CPXXgetnodeleftcnt/CPXgetnodeleftcnt accesses the number of unexplored nodes left in the branch-and-cut tree.

CPXCNT  CPXXgetnodeleftcnt( CPXCENVptr env, CPXCLPptr lp )

int  CPXgetnodeleftcnt( CPXCENVptr env, CPXCLPptr lp )

Description

The routine CPXXgetnodeleftcnt/CPXgetnodeleftcnt accesses the number of unexplored nodes left in the branch-and-cut tree.

Arguments

env
A pointer to the CPLEX environment as returned by CPXXopenCPLEX/CPXopenCPLEX.
lp
A pointer to a CPLEX problem object as returned by CPXXcreateprob/CPXcreateprob.

Return

If no solution, problem, or environment exists, CPXXgetnodeleftcnt/CPXgetnodeleftcnt returns 0 (zero); otherwise, CPXXgetnodeleftcnt/CPXgetnodeleftcnt returns the number of unexplored nodes left in the branch-and-cut tree.

Example


 nodes_left = CPXgetnodeleftcnt (env, lp);
