Simulated Contest Summary: DP, Graph Construction, and Matrix Optimization
Summary Time Allocation Nothing much to say; I sat through the entire contest, with some random submissions in between, essentially playing the IOI format. Exam Reflection Although the problems in this contest were quite challenging and had low discrimination, there were still some points I failed t...

Summing Weighted Unicyclic Subgraphs via Bitmask DP and Inclusion-Exclusion

Given an undirected graph (G=(V,E)) with (|V|=n \leq 16) and (|E| \leq \binom{n}{2}), compute the sum of weights of all unicyclic subgraphs. The weight of a unicyclic subgraph is defined as (2^w), where (w) is the number of non-leaf nodes in the subgraph. We first calculate cycle_count[S], the numbe...
