We are proud to present you our unique image comparison algorithm implemented as standalone dll file. It has only one exported function with two bitmap pointers in and similarity percentage out. Can work with many programming languages including Delphi, Visual C++, C#, VB and VB.NET. We can also provide you with the modified DLL. It can precalculate image hash (768 bytes) and you can use these hashes for comparison then. You can check our comparison algorithm with help of our Image Comparer tool.

Datum Locker allows the record keeping of account credentials and note taking which are deemed sensitive. Its strength comes from the use of an undocumented mathematically sound cryptographic algorithm to store your data on disk in addition to presenting an intruder with random semantics for the omittance of a valid key. Datum Locker operates on a timer monitoring when the application becomes idle, such a time will result in the application locking'n'docking onto the system tray. Datum Locker allows you to juggle your workstation notes and login accounts safely as behind the scenes a lock exists on this data using cryptography as it is fundamentally for your eyes only.

NSGA-II is a very famous multi-objective optimization algorithm. I submitted an example previously and wanted to make this submission useful to others by creating it as a function. Even though this function is very specific to benchmark problems, with a little bit more modification this can be adopted for any multi-objective optimization. The function is nsga_2(pop,gen). The input arguments for the function are population size and number of generations. For customization purposes the user is free to modify the objective function (function of several decision variables) by modifying an m file (evaluate_objective.

Gravitational search algorithm (GSA) is an optimization algorithm based on the law of gravity and mass interactions.This algorithm is based on the Newtonian gravity: "Every particle in the universe attracts every other particle with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them"..

The Jonker-Volgenant algorithm is much faster than the famous Hungarian algorithm for the Linear Assignment Problem (LAP). This Matlab implementation is modified from the original C++ code made by Roy Jonker, one of the inventors of the algorithm. It is about 10 times faster than the munkres code (v2.2) of the author. It can solve a 1000 x 1000 problem in about 3 seconds in a normal Intel Centrino processor. V1.1 returns the dual variables and the reduced cost matrix as well. V1.2 can deal with nonsquare assignment problems.

findMIS is an heuristic algorithm for solving Maximum Independent Set problem (MIS). An independent set of a graph is a subset of vertices in which no two vertices are adjacent. Given a set of vertices, the maximum independent set problem calls for finding the independent set of maximum cardinality. Algorithm run in O(n^2) time, where n is the number of vertices (worst case). Experimentally: time = 8.1e-007*n^2 + 2.2e-005*n + 0.00012 seconds, (see screenshot) The algorithm has been independently developped but is similar to: Balaji, Swaminathan, Kannan, "A Simple Algorithm to Optimize Maximum Independent Set", Advanced Modeling and Optimization, Volume 12, Number 1, 2010 Notation: The neighborhood of v is defined by N(v) ={u in V such that u is adjacent to v} The DEGREE of a vertex v in V, denoted by deg(v) and is defined by the...

This is an extremely fast implementation of the famous Hungarian algorithm (aslo known as Munkres' algorithm). The new version (V2.2)is about 1.5 times faster than the old version (V2.1). It can solve a 1000 x 1000 problem in about 20 seconds in a Core Duo (T2500 @ 2.00GHz) XP laptop with Matlab 2008a, which is about 2.5 times faster than the mex code "assignmentoptimal" in FEX ID 6543, about 6 times faster than the author's first version in FEX ID 20328, and at least 30 times faster than other Matlab implementations in the FEX.
