Cologne: A Declarative Distributed Constraint Optimization Platform

Summary: Cologne: a declarative COP platform for specifying and incrementally executing optimization problems across nodes. It fuses declarative networking (Colog) with a standard solver, merging Datalog with top-down constraint solving for fast, flexible COPs. (summarized by gpt-5-nano on Feb 09 2026)
