Use these algorithm-types with the parameters Cplex.IntParam.RootAlg, and Cplex.IntParam.NodeAlg, to specify which algorithm to apply during branch-and-cut search. In the case of Cplex.IntParam.RootAlg, the algorithm-type specifies the algorithm that solves the root relaxation. In the case of Cplex.IntParam.NodeAlg, the algorithm-type specifies the algorithm that solves the problems at other nodes. These parameters can be set with the method Cplex.SetParam.

These algorithm-types are also returned by Cplex.GetAlgorithm to report the algorithm that was used to generate the current solution.
