Competitive Programming Strategies: Tree Flow Balancing, Optimal Routing, and Game Theory
Tree-Based Resource Distribution
When distributing a fixed quantity of resources across a tree structure where each node must eventually hold an equal amount, removing any edge partitions the graph into two independent substructures. Let the total resource sum be $S$ and the number of nodes be $N$. The target allocation per node is $k = S / N$. ...

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 ...
