MaxIterations

MaxIterations
is an option that specifies the maximum number of iterations that should be tried in various built-in functions and algorithms.

Limit the number of iterations attempted in numerical minimization:

Out[1]=

Limit the number of iterations attempted in numerical minimization:

Out[1]=

MaxIterations can be infinite:

Limit or increase the number of steps taken with MaxIterations:

The default number of iterations for FindRoot is 100:

Eventually the algorithm stalls out since this mollifier function has all derivatives 0 at

Use a limited number of iterations to select candidates for a global minimum:

Find the minimum to 10 digits using arbitrary-precision arithmetic:

This can be done automatically with NMinimize:
