What problem does it solve?

Logic programming has many successors and variants beyond Prolog. This Skill helps developers understand the landscape, compare languages, and choose the right tool for specific reasoning, analysis, or constraint problems.

Core Features & Use Cases

• Datalog: termination-guaranteed querying on relations with a simplified, safe subset of Prolog concepts.
• miniKanren: logic programming embedded as a library inside existing languages, enabling relational queries without a new runtime.
• ASP/Clingo: constraint-based problem solving via answer-set programming for planning, configuration, and optimization.
• Constraint Logic Programming (CLP): integration of constraint solvers (e.g., finite domains, real numbers) with logical reasoning.
• Mercury, Curry, Verse: modern, typed or hybrid languages that bring performance, determinism guarantees, and nondeterministic semantics to logic programming.
• When to choose: guidance on selecting the right tool for static analysis, program reasoning, configuration, or game scripting depending on requirements.

Quick Start

Provide a concise, side-by-side comparison of two languages (e.g., Datalog and miniKanren) with a brief example illustrating their use.
