How felipe783/problema_papai-noel works

This repository implements a finite Santa Claus synchronization simulation in C/pthreads, with a separate infinite, interactive variant. The main workflow parses a run configuration, starts Noel, elf and reindeer threads, resolves group-help versus reindeer-trip requests, then computes metrics and exports CSVs. The README also documents experiment and graph-generation capabilities. The graph includes the infinite variant’s runtime and web interface; its server-to-simulator wiring is not shown in the sampled source, so that relationship is marked unverified.
