Hello all, This is the last assignment of the year for me. Each cell a ij of an adjacency matrix contains 0, if there is an edge between i-th and j-th vertices, and 1 otherwise. You can set amount of random holes that will be digged (spaceMin, spaceMax) and its size (spaceSize) You can set whether maze is symmetric on x, y or both axis. If other operations are important, we can optimize them by augmenting the adjacency list representation; for example, using sorted arrays for the adjacency lists reduces the cost of edge existence testing to O(log(d + (u))), and adding a second copy of the graph with reversed edges lets us find all predecessors of u in O(d-(u)) time, where d-(u. txt) or view presentation slides online. The Java programming language, developed by Sun Microsystems, is a language aimed at allowing "high-performance", virtual application development.
