When confronted to a clustering problem, one has to choose which algorithm to run. Building a system that automatically chooses an algorithm for a given task is the algorithm selection problem. Unlike the well-studied task of classification, clustering algorithm selection cannot rely on labels to choose which algorithm to use. However, in the context of constraint-based clustering, we argue tha...

In this paper, an optimal control of quadratic performance index with nonlinear constrained is presented. The sine-cosine wavelet operational matrix of integration and product matrix are introduced and applied to reduce nonlinear differential equations to the nonlinear algebraic equations. Then, the Newton-Raphson method is used for solving these sets of algebraic equations. To present ability ...

We develop and analyze numerical discretization to the constrained high-index saddle dynamics, dynamics searching for points confined on high-dimensional unit sphere. Compared with without constraints, has more complex dynamical forms, additional operations such as retraction vector transport are required due constraint, which significantly complicate scheme corresponding analysis. Furthermore,...

abstract effect of selection index in four iranian commercial lines (107, 110, 153 and 154) on performance of their hybrids including 107 ×110, 110×107, 153×154 and 154×153 was investigated. selection index program was performed on all 3p commercial lines during 9 generations. next generation parents of 3p lines were selected in each generation, by construction of selection matrix based on heri...
