Watch this video to learn more about the use of MultiStart for solver functions (maximize, minimize, find, minerr) in PTC Mathcad Prime 12.0.0.0:

MultiStart is a solving option you can select for the solver functions maximize, minimize, find, and minerr in PTC Mathcad Prime 12.0.0.0. MultiStart makes the nonlinear solver attempt to find a global maximum or minimum within the feasible region, rather than a local one. This way, it can be used to increase the probability of finding a valid solution for your calculations.
