Counting complexityComplexity dichotomySurjective homomorphismsMany graph parameters can be expressed as homomorphism counts to fixed target graphs; this includes the number of independent sets and the number of k-colorings for any fixed k. Dyer and Greenhill (RSA 2000) gave a sweeping complexity ...
We reduce the problem to deciding satisfiability of a CNF. Our reduction preserves the number of variables of the input formula and thus also preserves the exponential complexity of approximate counting. Our algorithm is also similar to an algorithm which works particularly well in practice and for...

We need a better method to evaluate and compare the running time of algorithms for any size of input. (See Insertion Sort and Lists for more examples of counting the number of operations.) Time Complexity Instead of looking at the exact number of operations an algorithm will perform, we ...

Sorting algorithm, in computer science, a procedure for ordering elements in a list by repeating a sequence of steps. Sorting algorithms allow a list of items to be sorted so that the list is more usable than it was, usually by placing the items in numer

Tabling itself comes at a cost: breadth first search has exponential (asymptotic) space complexity. In real terms this means that, for hard learning problems, where the proof tree built by Vanilla during Resolution grows too large, Prolog will run out of RAM for tabling. This can be ...
hi! this is a sorting algorithm I came up with the other day. it's for integer sorting but I suppose you could sort any set, all you have to do is write an order preserving mapping from your set to a set of integers. It has O(n*k) time complexity and O(n*m) space complexit...
“sufficient and nearly necessary” set of conditions under which the probability can be factorized into the product of an overall factor and the contributions from regions separated by gapless columns of the alignment, thus providing a sort of generalized HMM. The conditions distinguish evolutionary ...
