Smearing algorithm for vehicle parking management s ystem l. Matlab code matlab is a commonly used program for computer modeling. At each step, the genetic algorithm randomly selects individuals from the current population and uses them as parents to produce the children for the next generation. Since the edges in the center of the graph have large weights, the shortest path between nodes 3 and 8 goes around the boundary of the graph where the edge weights are smallest. As shown in example if 1 represent white pixel and 0 represent black pixel then sending whole matrix only runs of data count are stored in one matrix and only that matrix is sent. It replaces sequences of the same data values within a file by a count number and a single value.
