Maximum Number of Minor Iterations

Type

Integer

Range

{1..10000000}

Default

40

This is the maximum number of minor iterations allowed between successive linearizations of the nonlinear constraints. A moderate value (e.g., 10 ≤ k ≤ 50) prevents excessive effort being expended on early major iterations, but allows later subproblems to be solved to completion.

In general it is unsafe to specify a value as small as k = 1 or 2. (Even when an optimal solution has been reached, a few minor iterations may be needed for the corresponding subproblem to be recognized as optimal.)

Note that the global solvers option Iteration Limit defines (in case of MINOS) an independent limit on the number of major iterations. (A major iteration consists of a linearization of the nonlinear constraints.)
