# Optimize a FlxFunction

Registered by

It might be possible that a function of type FlxFunction can be optimized by reordering its terms.

However, it is tricky to write an algorithm dealing with that.

The information on how intensively to optimize a function should be given by default and by an optional argument at the end of a function.

NOTE: a basic optimization function has already been implemented

- try to rearange groups (+-*/) so that you can calculate some numbers

- ...

- try to find something like cosĀ²+sinĀ² (=1) ...

- optimize Matrix-Functions

- operators with 2 elements -> special version if one operant is a number

- is a memory optimization possible ??? This would be very important !!!

evaluation of constants WILL cause trouble with e.g. integ,root,sum
