Set an initial value (start value) for a variable.

The following sets an initial value of 0 for variable x. For y its solution from the preceding optimization is set as its new initial value.

setinitval(y, getsol(y))

This procedure sets an initial value for a decision variable. Initial values are used by nonlinear solvers as a (good) starting point for the search. It is in general not required that the initial values be part of a feasible solution to the optimization problem. All previously set initial values can be removed by calling clearinitvals. The procedure copysoltoinit can be used to turn the solution of a previous optimization run into initial values for the next run.

clearinitvals, copysoltoinit.
