Legendre wavelet method combined with the Gauss quadrature rule for numerical solution of fractional integrodifferential equations
(20220301)In this paper, we use a novel technique to solve the nonlinear fractional VolterraFredholm integrodifferential equations (FVFIDEs). To this end, the Legendre wavelets are used in conjunction with the quadrature rule for ...

Using Mott polynomials operational matrices to optimize multidimensional fractional optimal control problems
(20220301)We offer a method for solving the fractional optimal control problems of multidimensional. We obtain a fractional derivative and multiplication operational matrix for Mott polynomials (Mpolynomials). In the proposed ...

A heuristic algorithm to combat outliers and multicollinearity in regression model analysis
(20220301)As known, outliers and multicollinearity in the data set are among the important diffculties in regression models, which badly affect the leastsquares estimators. Under multicollinearity and outliers' existence in the data ...

Heuristic solutions for intervalvalued games
(20220301)When we design the payoff matrix of a game on the basis of the available information, then rarely the information is free from impreciseness, and as a result, the payoffs of the payoff matrix have a certain amount of ...

Connected bin packing problem on traceable graphs
(20220301)We consider a new extension of the bin packing problem in which a set of connectivity constraints should be satisfied. An undirected graph with a weight function on the nodes is given. The objective is to pack all the nodes ...

Fitted numerical method for singularly perturbed semilinear threepoint boundary value problem
(20220301)We consider a class of singularly perturbed semilinear threepoint boundary value problems. An accelerated uniformly convergent numerical method is constructed via the exponential fitted operator method using Richardson ...

Multiple interpolation with the fastgrowing knots in the class of entire functions and its application
(20220301)The conditions for the sequence of complex numbers (bn,k) are obtained, such that the interpolation problem g(k1)(λn) = bn,k, k ∈ 1, s, n ∈ N, where λk/λk+1 ≤ ∆

Preconditioned global GPBiCG method for solving saddle point problems with multiple righthand sides and its convergence analysis
(20220301)We propose the preconditioned global generalized producttype method based on the preconditioned global BiCG method to solve nonsymmetric saddle point problems with multiple righthand sides. We apply an indefinite ...

Numerical approximation for inverse problem of the Ostrovsky–Burgers equation
(20220301)This article considers a nonlinear inverse problem of the Ostrovsky–Burgers equation by using noisy data. Two BSplines with different levels, the quintic Bspline and septic Bspline, are used to study this problem. For ...

Asymptotic and numerical methods for solving singularly perturbed differential difference equations with mixed shifts
(20220301)This article deals with an effcient approximation method named successive complementary expansion method (SCEM) for solving singularly perturbed differentialdifference equations with mixed shifts. It is compared with the ...

Numerical solution of a system of Volterra integral equations in application to the avian human influenza epidemic model
(20220301)We propose an effcient multistage method for solving a system of linear and nonlinear Volterra integral equations of the second kind. This numerical method is based on the Gauss–Legendre quadrature rule that obtains several ...

Modified ADMM algorithm for solving proximal bound formulation of multidelay optimal control problem with bounded control
(20220301)This study presents an algorithm for solving optimal control problems with the objective function of the Lagrangetype and multiple delays on both the state and control variables of the constraints, with bounds on the ...
