GIGL: A Domain Specific Language for Procedural Content Generation with Grammatical Representations
Tiannan Chen, Stephen J. Guy · Proceedings of the AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment · 2018
We introduce a domain specific language for procedural content generation (PCG) called Grammatical Item Generation Language (GIGL). GIGL supports a compact representation of PCG with stochastic grammars where generated objects maintain grammatical structures. Advanced features in GIGL allow flexible customizations of the stochastic generation process. GIGL is designed and implemented to have direct interface with C++, in order to be capable of integration into production games. We showcase the expressiveness and flexibility of GIGL on several representative problem domains in grammatical PCG, and show that the GIGL-based implementations run as fast as comparable C++ implementation and with less code.
