Page Replacement Algorithm Visualizer

Compare FIFO, LRU, and Optimal replacement strategies against the same reference string and frame count.

To begin, specify the number of page frames to allocate. Next, click the random button to generate a random page-reference string. You can also adjust the number of random page strings to generate. Finally, click the calculate button to visualize the results.
