Using Fregean terms: whenever their presuppositions hold, the two hypotheses have the same referent ( truth-value ), but different senses ; that is, they express two different ways to determine that truth-value.

Using a little linear algebra, one can fairly easily construct approximations, which sample an arbitrary number of points to the left and a ( possibly different ) number of points to the right of the center point, for any order of derivative.

Using optimization algorithms, a circle-packing figure can be computed for any uniaxial base of arbitrary complexity.

Using Landau symbols, the worst case running time of CYK is, where n is the length of the parsed string and | G | is the size of the CNF grammar G. This makes it one of the most efficient parsing algorithms in terms of worst-case asymptotic complexity, although other algorithms exist with better average running time in many practical scenarios.

Using Fibonacci heaps for priority queues improves the asymptotic running time of important algorithms, such as Dijkstra's algorithm for computing the shortest path between two nodes in a graph.

Using key stretching algorithms, such as PBKDF2, to form password hashes can significantly reduce the rate at which passwords can be tested.

Using the same ideas used in minimum / maximum algorithms, we can construct a simple, but inefficient general algorithm for finding the kth smallest or kth largest item in a list, requiring O ( kn ) time, which is effective when k is small.

Using a computer for playback and / or processing potentially allows a broader choice of video players and / or editing software not limited to the quality offered by the embedded consumer electronics device, so at least theoretically higher dinterlacing quality is possible – especially if the user can pre-convert interlaced video to progressive scan before playback and advanced and time-consuming deinterlacing algorithms ( i. e. employing the " production " method ).

Using proprietary algorithms, it then determines how to lay these parts out in such a way as to produce the required quantities of parts, while minimizing the amount of raw material wasted.

Using fast algorithms for modular exponentiation, the running time of this algorithm is O ( k · log < sup > 3 </ sup > n ), where k is the number of different values of a we test.
