Hi,
I've run into a couple of problems trying to get simulated-annealing-examples to run; they both have to do with the sample generic function.
The first problem is that trivial-example-step calls sample with 'uniform as an argument instead of :uniform. I've attached a patch to fix this (although a patch is probably overkill since it's such a trivial fix).
The second problem is trickier, and I don't quite know what to do about it. Basically, only the mpointer of the random-number-generator that is passed to simulated-annealing is passed through to simulated-annealing-int, which means that only the mpointer is passed to trivial-example-step. This results in an error when trivial-example-step tries to call sample on the passed-in mpointer, because sample only has methods defined for random-number-generators.
I tried changing sa-step-function to wrap the mpointer in a random-number-generator before passing it through to the user-step-function, but that seems to cause memory problems (I think the wrappers free the underlying random number generator too many times when they get garbage-collected).
Has this sort of problem been fixed elsewhere in the codebase? If not, does anyone have any ideas about how to fix this?
Thanks, James
