TimeConstraint

TimeConstraint
is an option for various algorithmic functions that specifies how long to spend trying a particular transformation or part of an algorithm.

DetailsDetails

  • TimeConstraint->t specifies that a maximum of t seconds of CPU time should be spent 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.

This takes a long time, due to trigonometric expansion, but does not yield a simplification:

In[1]:=

Out[1]=

TimeConstraint limits the time spent on any single transformation:

In[2]:=
Click for copyable input
Out[2]=

A similar example, where the transformation yields a simplification:

In[1]:=
Click for copyable input
Out[1]=

In this case setting TimeConstraint prevents some simplification:

In[2]:=
