1. Sparse Linear Algebra The constraint matrices that arise in linear programming are typically extremely sparse. Sparse matrices contain very few non-zero entries. It is not unusual to find constraint matrices containing only 3 or 4 non-zero values per columns of A. The steps of both the sim...

The central problem of linear algebra is to solve a system of equations. Two equations with two variables can be visualized by row picture and column picture. The row picture shows two lines meeting at a single point and each equation is regarded as a line. The column picture combines the ...
parametric programming/ B0260 Optimisation techniques B0210 Algebra C1180 Optimisation techniques C1110 AlgebraWe designed an algorithm for the multiparametric 0–1-integer linear programming (ILP) problem with the perturbation of the constraint matrix, the objective function and the right-hand side ...

In the interest of being compact (and again, building toward the general linear programming formulation) we can extract the price information into a single cost vector c=(0.381,0.1,0.272), and likewise write our variables as a vector x=(b,m,r). We’re implicitly fixing an ordering on the...

In general, all our vectors and matrices will be 1-indexed. Note that for some programming languages, the arrays are 0-indexed. Matrices are usually denoted by uppercase names while vectors are lowercase. "Scalar" means that an object is a single value, not a vector or matrix. ...
