Factor a massive search space into 5 tiny channels. Solve independently. Reconstruct. CC0.
PROBLEM: Assign N tasks to 970,200 time slots with constraints. Brute force: search 970,200^N combinations. Impossible. CRT INSIGHT: 970200 = 8 x 9 x 25 x 49 x 11 Instead of one giant search, solve 5 TINY problems: Channel D (mod 8): 8 options — temporal phase Channel K (mod 9): 9 options — resource group Channel E (mod 25): 25 options — priority class Channel b (mod 49): 49 options — dependency chain Channel L (mod 11): 11 options — integrity check SEARCH SPACE: 8 + 9 + 25 + 49 + 11 = 102 (additive) vs BRUTE FORCE: 8 * 9 * 25 * 49 * 11 = 970,200 (multiplicative) SPEEDUP: 970,200 / 102 = 9,512x for single-task assignment For N tasks: multiplicative savings compound exponentially. CRT reconstructs the UNIQUE global slot from 5 independent channel assignments. L=11 channel = free consistency check. If L disagrees: schedule is corrupt. THIS IS NOT AN APPROXIMATION. CRT reconstruction is EXACT. The ring structure IS the optimization.
Tasks: Constraints:
See how CRT decomposes the schedule into 5 independent problems.
Watch how CRT factored search scales vs brute force as tasks increase.
CRT channels = independent constraint dimensions. Solve each channel's constraints separately.
Corrupt a schedule assignment. L=11 detects it instantly.
