Worked on enhancing the robustness of the NetLogo/NetLogo parser by addressing a critical issue related to global variable naming. Focused on backend development using Scala, the work introduced explicit error handling to prevent users from assigning string or numeric values as global variable names, which previously caused parser crashes. This solution improved stability for user scripts that depend on global state and provided clearer feedback to guide users toward correct usage. By enforcing strict naming validation and incorporating comprehensive unit testing, the changes reduced error rates and support overhead, contributing to the overall reliability of complex models built with NetLogo.
