This is a library of Java algorithms by indy256. There are 192 files with algorithms!
All algorithms are divided into groups. Each algorithm has description.
You can choose one of 73 syntax highlighting styles and one of 9 fonts. Also you can choose ont of 3 application themes for comfortable work.

The following topics are covered:
Trees: segment tree Fenwick tree k-d tree R-tree metric tree quadtree persistent tree link/cut tree binary heap disjoint-sets treap.
Graph algorithms: shortest paths maximum flow maximum matching spanning tree connectivity biconnectivity LCA.
String algorithms: suffix tree suffix automata suffix array trie Aho-Corasick algorithm Knuth-Morris-Pratt algorithm Z-function hashing parsing.
Sorting algorithms: quick- merge- heap- bubble- selection- insertion- counting- radix-sorting; Kth order statistic.
Geometry algorithms: segments/lines/circles intersection point in polygon query convex hull closest/furthest pair of points.
Combinatorics: permutations combinations arrangements partitions.
Other: big numbers multiplication via fast Fourier transform simplex algorithm.
