    gundercrypt [MOVED]

    A CLI text encrypting/ciphering program and library for java

    ** MOVED: to github.com/gundermanc/gundercrypt A CLI text ciphering program and library written in java that makes use of pseudo random numbers and a password (provided by the user) to generate encrypted text by selectively shifting each subsequent letter by a pseudo-random index, encoding it as a letter stored in a hidden position within the String, and then re shifting the encrypted String again by numeric values deduced from a password to provide a dual layer of security. Easily can be imported into any java project or run via shell commands.

    jsprit

    Open source toolkit for solving rich vehicle routing problems

    jsprit is a java based, open-source toolkit for solving rich Traveling Salesman Problems(TSP) and Vehicle Routing Problems(VRP). It is lightweight, flexible and easy-to-use, and based on a single all-purpose meta-heuristic. Setting up the problem, defining additional constraints, modifying the algorithms and visualizing the discovered solutions is as easy and handy as reading classical VRP instances to benchmark your algorithm. It is fit for change and extension due to its modular design and a comprehensive set of unit and integration tests. Possibility to define additional stateless and stateful constraints/conditions to account for the richness of your problem. GraphHopper invests in an active open source community. Our flagships are the GraphHopper routing engine and jsprit, the toolkit for solving rich vehicle routing problems. We promote a fair & diverse mindset.
