Linear Programming in Infinite-Dimensional Spaces
TL;DR: In this article, the authors present linear programming in infinite-dimensional spaces and show that linear programming can be used to solve problems in the real world as well as in the virtual world.

The Transportation Problem and its Variants
TL;DR: For 54 unimodular linear programming problems it is shown that either (i) the objective function is unbounded, or (ii) the problem is infeasible, or the problem can be solved by solving a related transportation problem.

On the uniqueness of solutions to linear programs
TL;DR: In this article, the authors provide a constructive method of checking whether a linear programming problem has a unique feasible or a unique optimal solution, which requires the solution of only one extra LPP such that the original problem has alternative solutions if and only if the optimal value of the new LPP is positive.

Rational and integral k-regular matrices
Gautam Appa,Balázs Kotnyek +1 more
TL;DR: It is shown that the advantageous properties of totally unimodular matrices with respect to integral polyhedra can be carried over to rational k-regular matrices, and it is proved that a matrix A is k- regular if and only if the polyhedron P(A,b)={x:x?0,Ax≤b} is integral for all integral vectors b.
