python Programming Glossary: memoizeTime complexity of accessing a Python dict http://stackoverflow.com/questions/1963507/time-complexity-of-accessing-a-python-dict though the algorithm is quadratic. I use a dictionary to memoize values. That seems to be a bottleneck. The values I'm hashing.. a simplified version of the memoization function def memoize fun memoized def memo args key args if not key in memoized memoized.. version of the memoization function def memoize fun memoized def memo args key args if not key in memoized memoized key..
list of all paths from source to sink in directed acyclic graph [duplicate] http://stackoverflow.com/questions/3278481/list-of-all-paths-from-source-to-sink-in-directed-acyclic-graph all of source but not necessarily a parent of sink. If it memoized the answer for a given source and sink node it would be possible.. is wrong memo_dict dict if source_node sink_node # Don't memoize trivial case return frozenset source_node else pair source_node.. source_node sink_node if pair in memo_dict # Is answer memoized already return memo_dict pair else result set for new_source..

python resettable instance method memoization decorator http://stackoverflow.com/questions/4431703/python-resettable-instance-method-memoization-decorator a decorator for an instance method of a class that will memoize the result. This has been done a million times before However.. However I'd like the option of being able to reset the memoized cache at any point say if something in the instance state changes.. actually stuck. My code looks like so import time class memoized object def __init__ self func self.func func self.cache def..
Python - anyone have a memoizing decorator that can handle unhashable arguments? http://stackoverflow.com/questions/4669391/python-anyone-have-a-memoizing-decorator-that-can-handle-unhashable-arguments 'b' 1 'c' 'd' 2 'e' 3 'f' _level is the function I want to memoize to make this setup more scalable. As implemented without memoization.. in Alex Martelli Python Cookbook that show how to create a memoize decorator using cPickle for function that take mutable argument.. a link . EDIT Using the code that you have given and this memoize decorator _level MemoizeMutable _level equirements 'a' 'b'..
