This option sets the maximal number of restarts that PATH should make if it could not find a feasible solution. PATH first tries to find a feasible solution with the current settings of the options. If PATH fails it restarts the solving process by using different kind of option settings. The option settings corresponding to the restart numbers are given in the following table, where “residual” denotes a measure of how far the initial point (given to PATH) is from satisfying the complementarity conditions.
