Hi all, I am working on ways to implement local search meta-heuristics in Haskell. I need various test problems to experiment on, and this has resulted in me building various file parsers and data structures for these. Currently I have versions for SAT, TSP and a couple of more private file formats. The file parsers are designed to process files coming out of the TSPLIB and SATLIB repositories. I also want to extend this to cover scheduling and timetabling example problems. Since these are all related I was going to try to put them together into a single library and post them to Hackage, but I am not sure what to put them under. I assume that Data is for data structures, which is not quite right. I was thinking about something like Problems. as a top level point in a hierarchy. Does anyone have any other suggestions, as this seems a little odd as a name to me? Alternatively, does this already exist and I have just missed it? Cheers RS
