Usage Examples English

- The Hosoya index can be efficiently approximated to any desired constant
**approximation**ratio using a fully-polynomial randomized approximation scheme. - A more general
**approximation**algorithm attains a 2-factor approximation for the weighted case. - A minimax
**approximation**algorithm (or L∞ approximation or uniform approximation) is a method to find an approximation of a mathematical function that minimizes maximum error. - Sometimes there are
**approximation**algorithms to the optimization problem, but, using such an approximation might make the mechanism non-truthful. - More involved techniques show that there are
**approximation**algorithms with a slightly better approximation factor.

- In mathematics, least squares function
**approximation**applies the principle of least squares to function approximation, by means of a weighted sum of other functions. - Anomalous diffraction theory (also van de Hulst
**approximation**, eikonal approximation, high energy approximation, soft particle approximation) is an approximation developed by Dutch astronomer van de Hulst describing light scattering for optically soft spheres. - A simplicial
**approximation**is homotopic to the map it approximates. See simplicial approximation theorem for more details. - discuss the NP-completeness proof and also present both a constant factor
**approximation**algorithm and polynomial-time approximation scheme to find the clusters in this setting. - Hardness of
**approximation**theory deals with studying the approximation threshold of such problems.

- The Max-Cut Problem is APX-hard, meaning that there is no polynomial-time
**approximation**scheme (PTAS), arbitrarily close to the optimal solution, for it, unless P = NP. - There is a polynomial-time
**approximation**algorithm with a logarithmic approximation guarantee, More specifically, a polynomial-time approximation algorithm for domatic partition with the approximation factor [...] for a constant [...] would imply that all problems in NP can be solved in slightly super-polynomial time [...]. - 1 + "ε"
**approximation**is to find a solution with approximation factor no greater than 1 + "ε". - The best
**approximation**known for the general problem achieves an approximation ratio of 2, and is by [...]. This approximation relies heavily on the primal-dual schema of [...].
