Some classes of variables can be lagged; that is, their value at each observation is remembered, and previous values can be referred to by the lagging functions. Other classes have only a single value ...

This is how variables work in programming. A variable is a label (usually a word) that can be substituted for a piece of data. This then allows us to ferry information around our app by getting ...

A new procedure for mixed integer programming is presented. It is applicable where the integer variables must be either zero or one, and where the integer variables are divided into sets such that the ...

The branch-and-bound method with the revised dual simplex for bounded variables is very effective in solving relatively large-size integer linear programming problems. This paper, based on the general ...
