WebDer Heapsort wurde von Robert W. Floyd und J. W. J Williams entwickelt. Er gehört zu den instabilen Sortieralgorithmen in der Informatik, arbeitet dabei aber nach dem in-place -Prinzip. Die Funktionsweise basiert eigentlich hauptsächlich auf binären Heap Eigenschaften als zentrale Datenstruktur und ist dabei ein fast vollständiger binärer Baum.
