Laboratory Exercise in Linear Programming

Abstract. The object of this poster presentation is to show a new approach to computer exercises in the course: Linear Programming. The exercises shall be organized in a computer lab for one group of students who will start the program within the Scriptrunner system. The program shall be performed over a WEB browser and student need no other program which might be installed on a lab's computer. A program has been developed for them there (in the same way as for any other types of math/computer exercises) and it shall set assignment(s) to students and shall require their solution and correct results. However, instead of a total program code which has to be supplied (written and executed) by a student, only a part of the program code shall appear, with certain parts missing. A student shall have to ll in the missing code part and start the execution. The screen area is divided into an input code - which is visible and shall be amended by additional data, and into an output code - in which after execution a solution appears. A student may solve the problem step-by-step, by the entry of the missing parts of the program code and watch whether he/she obtained the correct results. Only after he/she lls in correctly all invisible spaces by a missing program code he/she will get a con rmation and a grade for the successfully solved assignment. The Supervisor of the exercises shall be able to control any time over his web interface ; nally he will grade on-line all students' assignments. For those students that were not able to solve the task correctly, he will enable them to 'see the correct results'. For laboratory exercises in linear programming the simplex and interior-point method cases (author's diploma work) with the necessary programs written in Matlab were interpreted. (
