How My Two-Year-Old Taught Me Constraint Solving with Brio Trains

My two year old taught me constraint solving

While building Brio train layouts for my toddler, I discovered a complex algorithms problem hidden in our playtime. As we experimented with curves, straights, and crossings, my son's intuitive problem-solving mirrored sophisticated constraint satisfaction techniques. I explored how backtracking, exponential search spaces, and graph theory apply to creating closed loops, realizing that even a two-year-old can demonstrate expertise in constraint solving.
