Whereas we do not wish to draw attention to our problems, preferring to focus on the positive, this page collects problems together, in pages organized by topic.

Kinds of problems

We differentiate among bugs, blunders, technical problems, algorithmic problems and other problems.

• *Blunders* are typos or errors that can be put right immediately by typographical correction.
• *Bugs* are errors that may be put right, and do not require major new coding, but more than simple typographical correction.
• *Technical problems* are ones we know pretty well exactly how to solve, but may require more time or money than we have available, or maybe we are just lazy.
• *Algorithmic problems* are cases where the best method of doing something is in some doubt, and requires study. Examples of algorthmic problems are: what is the best way to score a molecule given the constraints of fast docking?
• There are other problems too. If a problem can be classified as one of the above, that can be helpful.
