Effective Algorithms for Solving Trace Minimization Problem in Multivariate Statistics

the algorithm for solving the inverse numerical range problem

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.

Interruptible Algorithms for Multi-Problem Solving

In this paper we address the problem of designing an interruptible system in a setting in which n problem instances, all equally important, must be solved. The system involves scheduling executions of contract algorithms (which offer a tradeoff between allowable computation time and quality of the solution) in m identical parallel processors. When an interruption occurs, the system must report ...

Fast algorithms for solving H,-norm minimization problems

H,-norm of the approximation error for both methods satisfies 16, 91 In this paper we propose an efficient computational a p rn proach to minimize the H,-norm of a transfer-function OT+I 5 /IG(s) G,(s)/Im 1 2 x ai (2) matrix depending affinely on a set of free parame.=?+I ters. The minimization problem, formulated as a semiinfinite convex programming problem, is solved via a where > . . . > 0, ...

Heuristic Search Algorithms for Problem Solving

Introduction Modern problem solving applications usually rely on some heuristics to intelligible search thorough all possible solution to solve a given problem. Heuristics might not always find the best solution, but it is guaranteed to find a good solution in reasonable time [1]. This paper discusses the commercial application, the underlying technology of heuristic based searching, and how th...
