I am trying to use d_ary_heap_indirect. I was able to create an object of the queue, but I can't push a vertex into it. Here is what I tried:

I get a "no match for operator[]" error on the last line (the push()).

Can anyone see what is wrong with that example?

It looks (from the comments for d_ary_heap_indirect) that IndexInHeapMap needs to map from values (here, vertices) to indices, and so you probably need to use GridIndexMapType to create the IndexInHeapMap like you do for PriorityMapType. -- Jeremiah Willcock
