  This paper presents an interactive platform to interpret multi-objective
evolutionary algorithms. Sokoban level generation is selected as a showcase for
its widespread use in procedural content generation. By balancing the emptiness
and spatial diversity of Sokoban levels, we illustrate the improved two-archive
algorithm, Two_Arch2, a well-known multi-objective evolutionary algorithm. Our
web-based platform integrates Two_Arch2 into an interface that visually and
interactively demonstrates the evolutionary process in real-time. Designed to
bridge theoretical optimisation strategies with practical game generation
applications, the interface is also accessible to both researchers and
beginners to multi-objective evolutionary algorithms or procedural content
generation on a website. Through dynamic visualisations and interactive
gameplay demonstrations, this web-based platform also has potential as an
educational tool.
