XPRStune
XPRStune |
Purpose
This function begins a tuner session for the current problem. The tuner will solve the problem multiple times while evaluating a list of control settings and promising combinations of them. When finished, the tuner will select and set the best control setting on the problem. Note that the direction of optimization is given by
OBJSENSE.
Synopsis
int XPRS_CC XPRStune(XPRSprob prob, const char *flags);
Arguments
|
prob
|
The current problem.
|
||||||||||||
|
flags
|
Flags to pass to
XPRStune, which specify whether to tune the current problem as an LP or a MIP problem, and the algorithm for solving the LP problem or the initial LP relaxation of the MIP. The flags are optional. If the argument includes:
|
Example
XPRStune(prob, "dp");
This tunes the current problem. The problem type is automatically determined. If it is an LP problem, it will be solved with a concurrent run of the dual and primal simplex method. If it is a MIP problem, the initial LP relaxation of the MIP will be solved with a concurrent run of primal and dual simplex.
