Systems of Linear Equations with Non-Negativity Constraints: Hyper-Rectangle Cover Theory and Its Applications

In this paper, a novel hyper-rectangle cover theory is developed. Two important concepts, the <i>cover order</i> and the <i>cover length</i>, are introduced. We construct a specific échelon form of the matrix in the same manner as that employed to determine the rank of the ma...
