is an option for various functions that specifies how long to spend doing a particular operation.
- TimeConstraint->t specifies that a maximum of t seconds of CPU time should be spent doing a particular operation, or trying a particular transformation or part of an algorithm.
- TimeConstraint->Infinity specifies that there should be no limit on the CPU time allowed.
- In functions such as Simplify and FullSimplify, settings for TimeConstraint give only the maximum time to be spent doing a particular transformation on a particular subpart; the total time spent processing the whole expression may be considerably larger.
- Changing the setting for TimeConstraint will never affect the validity of a result obtained from functions like 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.
TimeConstraint limits the time spent on any single transformation:
In this case, setting TimeConstraint prevents some simplification:
