Just curious, but without my references im not really sure but what kind of heap is that? Fibonnacci?
Assuming you are referring to the EoPwP heap that educated_foo
points to, then (as stated by educated_foo, who refers to me in the
plural :-) it is strictly a simple, array-based implementation of a
binary heap. It isn't documented except as it is built in the book.
A main difference between this and the Heap model is that
this one contains the comparison routines internally and works on the
model of selecting a comparison method on heap creation and supplying
a suitable key and satellite data for each inserted element (it is
easy to use any objects for which you can supply a key) --- to use
objects with the Heap version you need all of your objects
to supply their own cmp() method for comparing themselves with any
other object type in the heap. The latter is more flexible because
the comparison routines may be arbitrarily complex, but does require
that all your objects either inherit or supply their own common
