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 +...
This function contains the well known greedy algorithm for solving Set Cover problem (ChvdodAtal, 1979), with two small modifications: * In case of more than one possible choice at a certain step, the biggest set is chosen; * Once the...
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....
In Model-in-the-Loop for Embedded System Test (MiLEST) the developed signal-feature d-deOCt oriented paradigm allows the abstract description of signals and their properties. It addresses the problem of missing reference signal flows as well as...
