1. Heap Layers
- www.cs.umass.edu
- Heap Layers provides a flexible infrastructure for composing high-performance memory allocators out of C++ "layers". Heap Layers makes it easy to write high-quality custom and general-purpose memory allocators. ...
- Heap Layers contains a number of ready-made heap components that can be plugged together with minimal effort, and the result is often faster than hand-built allocators. ...
- Very importantly, we've shown that Heap Layers can substantially outperform its only real competitor, the Vmalloc package from AT&T (the "Reconsidering Custom Memory Allocation" paper has more details). Not only is Heap Layers much higher level and simpler to use, but its clever use of templates also improves performance. Heap Layers both eliminates the function call overhead imposed by Vmalloc layers and yields higher quality code by exposing more optimization opportunities.

2. Sorting with a Heap
- www.brpreiss.com
- Sorting with a Heap.
- In this section we present a version of selection sorting that uses a binary heap to hold the elements that remain to be sorted. ... The principal advantage of using a binary heap is that it is easily implemented using an array and the entire sort can be be done in place. ...
- As explained in Section , a binary heap is a complete binary tree which is easily represented in an array. The n nodes of the heap occupy positions 1 through n of the array. ...
- In the first phase, the unsorted array is transformed into a heap. ... In this case, a max-heap rather than a min-heap is used. The data in a max heap satisfies the following condition: For every node in the heap that has a parent, the item contained in the parent is greater than or equal to the item contained in the given node. ...
- The sorted list is built by repeatedly selecting the largest element, withdrawing it from the heap, and adding it to the sorted sequence. As each element is withdrawn from the heap, the remaining elements are heapified. ...
3. The Event Heap
- graphics.stanford.edu
- The Event Heap: An Enabling Infrastructure for Interactive Workspaces.
- We propose the Event Heap as a novel mechanism by which multiple users, machines and applications can all simultaneously interact as consumers and generators of system events. The Event Heap is flexible, robust to failure of individual interactors, and sufficiently lightweight to be integrated easily with "legacy" single-user-GUI applications.
4. Data Structures and Algorithms: Heaps
- ciips.ee.uwa.edu.au
- A binary tree has the heap property iff .
- the key in the root is larger than that in either child and both subtrees have the heap property. ...
- A heap can be used as a priority queue: the highest priority item is at the root and is trivially extracted. But if the root is deleted, we are left with two sub-trees and we must efficiently re-create a single tree with the heap property. The value of the heap structure is that we can both extract the highest priority item and insert a new one in O(logn) time. ...
- Let's start with this heap. ...
- To work out how we're going to maintain the heap property, use the fact that a complete tree is filled from the left. ...
- The left subtree has now lost the heap property. ...
- This tree is now a heap again, so we're finished. ...
- We need to make at most h interchanges of a root of a subtree with one of its children to fully restore the heap property. Thus deletion from a heap is O(h) or O(logn). Addition to a heap.
- To add an item to a heap, we follow the reverse procedure. ...
- Then the 'fill from the left' nature of the complete tree ensures that the heap can be stored in consecutive locations in an array. ...
- The code for extracting the highest priority item from a heap is, naturally, recursive. ...
- Inserting into a heap follows a similar strategy, except that we use a MoveUp function to move the newly added item to its correct place. ...

- build-heap, heapify, heapsort, priority queue. ...
- See also binomial heap. ...
- A binary heap can be efficiently implemented as an array, where a node at index i has children at indexes 2i and 2i+1 and a parent at index i/2, with one-based indexing. ...
- Merging two binary heaps is O(n): the best you can do is just concatenate two heap arrays and make a heap of the result. ...

- Brian Heap.
- Professor Brian Heap is the former Foreign Secretary and Vice President of the Royal Society, and is Master of St. ...
- Recently Heap has chaired the Sense about Science Working Party on peer review which meets at the Royal Society. ...
- Although the Royal Society has been amongst Pusztai's sternest critics over the issue of speaking out about his findings prior to peer review, Heap has admitted that biotech companies often release their findings to the mass media before undergoing peer review in order to help keep up their share price. ...
- Heap helped produce the Royal Society report Genetically Modified Plants for Food Use which was used to reassure the Blair government that there were no significant problems with GM crops. ...
- Heap was also on the Royal Society group that organised a partial 'peer review' of Pusztai's work while it was still unpublished - an act The Lancet described as 'a gesture of breathtaking impertinence to the Rowett Institute scientists who should be judged only on the full and final publication of their work. ...
- Heap has been involved with bioethics at the European Commission and the Nuffield Council on Bioethics and, together with Derek Burke and Mike Gale , contributed to the Nuffield report on GM crops which contains an appendix which is highly critical of Pusztai. ...
- When the Lancet published Pusztai's research, after it had been successfully peer reviewed, Heap attacked the publication of the paper and claimed it showed that the rats were being starved and that this, and not the GM food in their diet, accounted for the damage they sustained. ...
- As a member of the Government's Expert Group on Cloning, Heap supported research on embryos and therapeutic cloning. According to Heap, producing embryos by nuclear transfer using the Dolly technique was a new way to learn more about ourselves and how to treat serious illnesses .

- Title: winnowing data with a heap. ...
- The winnow class uses a heap for finding the best few out .
- class winnow: """A heap structure allows you to easily keep track of one extreme of a set of values, at the expense of most other forms of order. ... The winnow heap is implemented as a fixed length list with the worst item at position 0. ... Because the length of its heap is unchanging and known in advance, the winnow can use shortcuts unavailable to the queue. ... The heap is initialised thus: self. heap = abject * length + target which already meets the heap invariant, saving the trouble of heapification. As data is thrown against the heap, it will fill up with real values. ... answer returns the heap with abject and target values stripped away. ... seq - optional iterable to initialise the heap. ... heap = abject * length + target if seq: self. ... If one is more suitable than the worst in the heap, it displaces it and triggers some shuffling in the heap to bring the new worst item to the fore. ... heap 0 ): pos = 0 while True: child = 2 * pos + 1 if child >= self.
- In row 7, both take in the B, as they should, but le propagates it down to the bottom of the heap, while lt leaves it at the top. ... heap child , self. heap child + 1 ): child += 1 instead of if self. ... heap child , self. heap child + 1 ): child += 1 or, to be overly concise child += self. ... heap child , self. heap child + 1 ) abject is there to ease the creation of a fixed length heap in the absense of real values. ...
