Description: Simulation operating system uses OPT, FIFO and LRU page replacement algorithm process. Let the program addresses the range of 0 to 32767, using a random number generator 256 instruction address, the address is to meet 50 of the order, a 25 jump forward, jump back 25 . To meet the above conditions, you can take the following methods: Let d0 10000, n-th instruction address is dn, the first n+1 instruction address dn+1, n the range of 0-255. 1-1024 each generate a random number within a range, if a falls within the range of 1-512, the dn+1 dn+1. If a falls within the range of 513-768, set dn+1 within the range of 1 to dn a random number. If a falls within the range of 769-1024, is set to dn dn+1 to a random number within the range of 32767. Page size in the range of 1K, 2K, 4K, 8K, 16K. Follow the page size of the instruction address into the page number. For the same adjacent page numbers, into one. Memory blocks allocated to the program in the range of 1, 2, until the page number
