Solving Subsequent LPs or QPs in a MIP
Parameter IloCplex.IntParam.RootAlg also controls the algorithm used for solving the first LP or QP when solving a MIP. The algorithm for solving all subsequent LPs or QPs is then controlled by parameter IloCplex.IntParam.NodeAlg. The same set of algorithm choices is available, with the exception of IloCplex.Algorithm.Sifting and IloCplex.Algorithm.Network in case of QPs.
