That's awesome. I'm really glad you did / are doing this. It's by far one of the most important steps in actually doing what I'm asking about. I think the time to make such a test suite should be considered in evaluating how feasible what I'm suggesting is. > Based upon > what > I've seen Maxima's integration is on the whole faster than FriCAS, but > has > the problem of requesting user input to narrow to one solution. > I'm willing to work with someone on this, but I'll have to wait until I > finish some of the contract work I'm doing.
