The future of feed formulation for poultry: Toward more sustainable production of meat and eggs

open access: yesAnimal Nutrition, 2023
Current methods for feed formulation are based on minimizing costs, not maximizing profits. Complex models of bird growth and reproduction as functions of genetic, feed and other environmental variables are being developed, but their adaptation has been ...

LINEAR PROGRAMMING AND DYNAMICS

open access: yesUral Mathematical Journal, 2015
In a Hilbert space we consider the linear boundary value problem of optimal control based on the linear dynamics and the terminal linear programming problem at the right end of the time interval.

A linear programming methodology for approximate dynamic programming

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2020
The linear programming (LP) approach to solve the Bellman equation in dynamic programming is a well-known option for finite state and input spaces to obtain an exact solution.

Decoding by Linear Programming [PDF]

open access: yes, 2004
This paper considers the classical error correcting problem which is frequently discussed in coding theory. We wish to recover an input vector $f \in \R^n$ from corrupted measurements $y = A f + e$.

Linear-quadratic programming and its application to data correction of improper linear programming problems

open access: yesOpen Computer Science, 2020
The problem of maximizing a linear function with linear and quadratic constraints is considered. The solution of the problem is obtained in a constructive form using the Lagrange function and the optimality conditions.

LINEAR PROGRAMMING APPLIED TO A CONVEX PROGRAMMING TYPE

open access: yesPesquimat, 2014
In the present’s paper studying a strategy for a typo of convex problem, we treat a linear programming problem whose coefficient of decision variables in the objective function has a nonlinear behavior.

Developments in linear and integer programming [PDF]

open access: yes, 2002
In this review we describe recent developments in linear and integer (linear) programming. For over 50 years Operational Research practitioners have made use of linear optimisation models to aid decision making and over this period the size of problems ...

0-1 Integer Linear Programming with a Linear Number of Constraints [PDF]

open access: yes, 2014
We give an exact algorithm for the 0-1 Integer Linear Programming problem with a linear number of constraints that improves over exhaustive search by an exponential factor.

SENSITIVITY ANALYSIS IN LINEAR-PLUS-LINEAR FRACTIONAL PROGRAMMING PROBLEMS [PDF]

open access: yesIranian Journal of Optimization, 2009
In this paper, we study the classical sensitivity analysis when the right - hand – side vector, and the coefficients of the objective function are allowed to vary.
