WebThe buddy algorithm maintains free lists of different sized blocks. When a request for memory is made these free lists are searched. If the appropriate size is not found a larger block is split (variations of this algorithm determine how the block is actually split, for example, in a binary buddy system the block is split by powers of two).

"WebWe propose several modifications to the binary buddy system for managing dynamic allocation of memory blocks whose sizes are powers of two. The standard buddy system allocates and deallocates blocks in $\Theta(\lg n)$ time in the worst case (and on an amortized basis), where n is the size of the memory. We present three schemes that … " - Binary buddy algorithm
