Algorithmic Problem Solving: Maximum Independent Set, Bomb Chain Reactions, SG Functions, and Tree Queries
A
Given a sequence ${a_n}$, select the largest possible subset such that no two selected elements sum to a prime number.
Constraints: $T \leq 4$, $n \leq 750$, $a_i \leq 10^9$.
Identical values can be merged into counts. Note that at most one instance of 1 may be included.
This becomes a bipartite graph problem: odd numbers connect to the sourc ...
