Chemical Reaction Optimization: Assembly, Parameters, and Test Results

Summary

This article assembles a population-based chemical reaction optimization algorithm from operators introduced in an earlier installment. It describes initialization, kinetic-energy scaling, and the selection of synthesis, intermolecular collision, decomposition, or single-molecule collision according to molecule fitness, collision counts, and parameters. The implementation tracks parent and offspring populations, updates the best solution, and applies operation-specific follow-up steps.

The reported evaluation compares CRO with other optimization methods on test functions and presents ranking and histogram visualizations. The author characterizes CRO as fast, scalable, and convergent across varied functions, while acknowledging that it can become trapped in local optima. The results are experimental and concern general optimization benchmarks, not financial market data or trading performance. The article also notes that its implementation adapts canonical algorithms, so conclusions may not transfer unchanged to other CRO versions or real-world objectives.

Key ideas

• CRO represents candidate solutions as molecules and changes them through several reaction operators.
• Kinetic energy is scaled using population fitness and the current global best to help select reactions.
• The algorithm maintains parent and offspring populations and updates the best candidate during revision.
• The article reports benchmark comparisons and describes the method as fast and scalable, but says it can get stuck in local optima.
• The implementation is an adapted optimizer, so its reported results do not establish trading effectiveness.
