My published chess problems

Here are some published chess problems that I composed with a computer. Most of them are proof games. I like proof games because the desired aesthetics are easier to program than for a typical "mate in n" problem. I say "composed with a computer" because really the computer is the one finding the problem. Still, it takes a lot of skills from my part to imagine problems that aren't trivial for humans to compose, yet do not require the age of the universe to compute. The problems are not necessarily better than the human-created ones, but the style is different.
