Defined in File lcp.cpp

Inheritance Relationships

Base Type

public GRBCallback (Class GRBCallback)

Class Documentation

class LCP_PATHStart : public GRBCallback 

A GRBCallback to warm start a feasible MIP solution with PATH. This is triggered whenever the number of explored nodes is greater than a given threshold.

Public Functions

inline LCP_PATHStart(MathOpt::LCP *LCPin, GRBVar *vars, unsigned long int numvars)

Default constructor.

Parameters

LCPin – Pointer to the LCP which is solved by Gurobi
vars – Pointer to the Gurobi variables
numvars – Number of variables

Public Members

bool done = false: If PATH was called at least one time.

unsigned long int minNodes = 2500: Threshold on the minimum number of explored nodes.

GRBVar *Vars = {}: Pointer to vars.

unsigned long int numVars: Number of vars.

MathOpt::LCP *LCP: Pointer to the LCP instance.

Protected Functions

inline void callback() override: Standard override for the Gurobi callback. This will try to generate the PATH’s solution if the number of nodes is greater than the given threshold.
