  • TimeConstraint is an option for Simplify and FullSimplify which gives the maximum number of seconds for which to try any particular transformation on any subpart of an expression.
  • The default setting for TimeConstraint is 300 (corresponding to 5 minutes) in Simplify and Infinity in FullSimplify.
  • Settings for TimeConstraint give only the maximum time to be spent in doing a particular transformation on a particular subpart; the total time spent in processing the whole expression may be considerably larger.
  • Changing the setting for TimeConstraint will never affect the validity of a result obtained from Simplify or FullSimplify, but smaller settings may prevent the simplest possible form from being found.
  • Since different computer systems run at different speeds, the same setting for TimeConstraint can lead to different results on different systems.
  • See the Mathematica book: Section 3.3.9.
