The new Hybrid Adams type Block Methods (HATBMs) for step length k=2,3 and 4 were developed for the solution of first order ordinary differential equations. Collocation and interpolation of Chebyshev polynomial approximation were adopted to derive some implicit linear multi-step...

In the present paper, we extend the results of [1] by applying hypergeometric series. We study local and global properties, Voronovskaja type asymptotic formula and error estimation for modified Beta operators. We also derive some other characteristics of these operators.

In this paper, we derive a new quarter-step hybrid block method for the solution of first-order Ordinary Differential Equations (ODEs). We employ the approach of interpolating the power series and collocating the differential system within a quarter-step interval of integration....

In the traveling salesman problem, there are a collection of cities and travel cost between each pair of them. The aim is to find the minimum cost way of visiting all cities and returning to the starting point. This kind of problem is deceptive and one of the most intensely studi...
