Optimal Algorithms for Finding the Symmetries of a Planar Point Set

نویسنده

  • Peter T. Highnam
چکیده

We present an asymptotically optimal algorithm to locate all the axes of mirror symmetry of a planar i t The algorithm was derived by reducing the 2-D symmetry problem to linear pattern-matching. Opt gorithms for finding rotational symmetries and deciding whether a point symmetry exists are also prese

A Thinning Method of Linear And Planar Array Antennas To Reduce SLL of Radiation Pattern By GWO And ICA Algorithms

In the recent years, the optimization techniques using evolutionary algorithms have been widely used to solve electromagnetic problems. These algorithms use thinning the antenna arrays with the aim of reducing the complexity and thus achieving the optimal solution and decreasing the side lobe level. To obtain the optimal solution, thinning is performed by removing some elements in an array thro...

PLASTIC ANALYSIS OF PLANAR FRAMES USING CBO AND ECBO ALGORITHMS

In rigid plastic analysis one of the most widely applicable methods that is based on the minimum principle, is the combination of elementary mechanisms which uses the upper bound theorem. In this method a mechanism is searched which corresponds to the smallest load factor. Mathematical programming can be used to optimize this search process for simple fra...

A Hybrid Algorithm using Firefly, Genetic, and Local Search Algorithms

In this paper, a hybrid multi-objective algorithm consisting of features of genetic and firefly algorithms is presented. The algorithm starts with a set of fireflies (particles) that are randomly distributed in the solution space; these particles converge to the optimal solution of the problem during the evolutionary stages. Then, a local search plan is presented and implemented for searching s...
