Develop a heuristic algorithm to add k sequential LLs in an N × N grid topology network, where k ? 1 and N ? R, to minimize the APL value. Compare the APL value, after adding k LLs with the heuristic algorithm, with respect to the APL value after adding the same number of LLs with the MinAPL-based LL addition algorithm. Make suitable assumptions.
