random replacement policy

Random replacement policy is a cache replacement algorithm where a cache block is selected for replacement randomly. In this policy, any block in the cache can be replaced at any time, regardless of how recently or frequently it has been accessed. This policy is simple to implement and does not require any additional bookkeeping, but it may not be the most effective approach for all caches. Random replacement can lead to cache thrashing, where frequently accessed blocks are evicted from the cache and then immediately reloaded, resulting in poor cache performance. However, it can be a useful policy in situations where there is no predictable pattern of memory access, such as in some scientific simulations or data analytics workloads.
