ILOG CPLEX .NET Reference Manual

Cplex.SolveCallback.UseSolution Method 

Instructs Cplex to use a solution.

protected virtual void UseSolution();

Remarks

This method instructs Cplex to use the solution generated with this callback instead of solving the node itself.

If useSolution is not called, Cplex uses the algorithm selected with parameter Cplex.IntParam.RootAlg or Cplex.IntParam.NodeAlg to solve the node.
