Gecode won the minizinc challenges from inception of the challenge in 2008 until 2012, but these days or-tools wins gold every year 2013 to 2024, and in 2024 swept gold in all categories.

Why is gecode interesting? Why use it over or-tools?

Interesting, but why post it? Nothing seems to have been committed/updated in about 6 years. There are a number of PRs outstanding. Is it still in use?

The forum implies that not much maintenance happened after the passing of the primary contributor, even if there were good intentions.

Are there other constraint solvers which have subsumed this one?

A short C++ example of gecode in use on their home page would be real nice.

For some reason I pictured this software as a system for developing memory or CPU constrained software. Like granting only 1 mb of memory and maybe having functions executed in a certain number of "clock ticks"
