I am writing an algorithm that takes objects (i.e. graphs with thousands of nodes) into a "hypothetical" state. I need to keep a history of these hypothetical objects depending on what happens to them later. Note that these hypothetical objects are intimately operated on, changed, and made otherwise significantly different from the objects they were copied from.
I've been using deepcopy to push the objects into the hypothetical state where I operate on them heavily. This is pretty slow since the objects are very large. Is there another way to do this without resorting to deepcopy? by the way, the algorithm works fine. It's just this part of it that I am trying to change. Thanks in advance. -- http://mail.python.org/mailman/listinfo/python-list
