Computer Composition Searches

A computer can be a useful tool to search for compositions, yet even with today's fast processors exhausting many composition searches is too big a task. This page has been created to keep a record of searches people have successfully completed in popular methods. If you have completely exhausted a computer search for compositions, please add an entry to the table below, stating any constraints you applied to the search, when you first ran it, and any other information you think would be of interest.
