The base class for user-written solve callbacks to control how subproblems (for example, node and heuristic subproblems) are solved within branch and cut.

Namespace: ILOG.CPLEX
Assembly: ILOG.CPLEX (in ILOG.CPLEX.dll) Version: 22.1.1.0

Syntax

C#
public abstract class SolveCallback : Cplex..::..ControlCallback
Visual Basic
Public MustInherit Class SolveCallback _
	Inherits Cplex..::..ControlCallback

Remarks

An instance of this class can be used to solve subproblems during a branch-and-cut search. It allows you to set a starting point when a node is being solved or to select the solution algorithm on a per-node basis.

The constructor and methods of this class are protected to make sure that they are used only to derive a user-written callback class or to implement the main method in it.
