Description:
<jats:p> In teaching linear programming in a classroom the instructor often makes numerical errors, which distract both students and instructor. Inexpensive and portable microcomputers allow real-time and error-free demonstrations of algorithms. One such system solves linear programming problems with up to 20 variables and nine constraints in an interactive conversation with a microcomputer. The continuous transformations of the linear programming tableaus can be viewed as the iterations proceed to find the optimal solution. The program is intended mainly as a teaching aid. </jats:p>
