Hipster4j - version 1.0.0-rc2

Welcome to Hipster4j docs. The aim of Hipster4j is to provide an easy to use yet powerful and flexible type-safe heuristic search library for Java and Android. Hipster4j relies on a flexible model with generic operators that allow you to reuse and change the behavior of the algorithms very easily. Algorithms are also implemented in an iterative way, avoiding recursion. This has many benefits: full control over the search, access to the internals at runtime or a better and clear scale-out for large search spaces using the heap memory.

You can use Hipster to solve from simple graph search problems to more advanced state-space search problems where the state space is complex and weights are not just double values but custom defined costs.

Why Hipster4j?

Surprisingly, there is a lack of Java libraries that implement search algorithms (such as Dijkstra or A*) with an extensible, flexible and simple to use model. In fact, most of the libraries rely on graph structures or recursive implementations which do not offer fine-grained control over the algorithm. It is very common to find many different projects (such as graph libraries, NoSQL databases, etc) reinventing the wheel each time they need to use a common search algorithm to solve a concrete problem.

Hipster4j aims to solve this problem by providing the common components of a search algorithm and a comprehensive set of classical search algorithms ready to be used in any kind of project.
