## DecayCounter.java
import java.util.HashMap;

/* A weighted counter that remembers most frequent and recent pairs on a 2-color graph, where:
 *  - any pair (a_i, b_i) contains elements a_i from set A and elements b_i are from set B.  A and B are disjoint.
 *
 * This counter basically implements a recurrence relation to maintain scores for each pair:
 *   score = memory * prev_score + (1-memory) * (+/-)1
 *
 * "memory" is a value between 0 and 1 chooses how much history history to take into account.
