An NP search problem is the problems of finding a witness to the given NP predicate, and TFNP is the class of total NP search problems. TFNP contains a number of subclasses conta...
We introduce a new stable minimum storage algorithm for merging that needs O(m log( n m + 1)) element comparisons, where m and n are the sizes of the input sequences with m ≤ n. ...
We consider the set Gn of all period sets of strings of length n over a finite alphabet. We show that there is redundancy in period sets and introduce the notion of an irreducibl...
We present a new conservative image-based occlusion culling method to increase the speed of hardware accelerated rendering of very complex general scenes which may consist of mill...
