This module offers facilities to turn off the builtin Math::Symbolic
|
|
simplification routines and replace them with routines that just clone the
|
|
objects. You may want to do this in cases where the simplification
|
|
routines fail to simplify the Math::Symbolic trees and waste a lot of CPU
|
|
time. (For example, calculating the first order Taylor polynomial of a
|
|
moderately complex test function was sped up by 100% on my machine.)
|
|
|
|
A word of caution, however: If you turn off the simplification routines,
|
|
some procedures may produce very, very large trees. One such procedure
|
|
would be the consecutive application of many derivatives to a product
|
|
without intermediate simplification. This would yield exponential growth
|
|
of nodes. (And may, in fact, still do if you keep the simplification
|
|
heuristics turned on because most expressions cannot be simplified
|
|
significantly.)
