Worst Fit allocates a process to the partition which is largest sufficient among the freely available partitions available in the main memory. If a large process comes at a later stage, then memory will not have space to accommodate it.
1- Input memory blocks and processes with sizes.
2- Initialize all memory blocks as free.
3- Start by picking each process and find the
maximum block size that can be assigned to
current process i.e., find max(bockSize,
processSize[current], if found then assign
it to the current process.
5- If not then leave that process and keep checking
the further processes.
Below is implementation of above steps.
// C++ implementation of worst - Fit algorithm
// Function to allocate memory to blocks as per worst fit
Process No. Process Size Block no.
