Title
On RoundOff Errors in Linear Programming (Lecture Notes in Economics and Mathematical Systems, 37),Used
Delivery time: 8-12 business days (International)
Due to the limited number of digits or bits per storage location in electronic computers, roundoff errors arise during arithmetic operations. Depending upon the kind of operation, the structure of the data, and the skillfulness of the program, these errors increase and spread out more or less quickly during a continued computation process in which the computed data affected by errors are themselves used for generating new data. The purpose of this investigation was to learn about the increase of roundoff errors in linear programming procedures. Less attention was paid to the theory of roundoff errors or to the effectiveness of error elimination procedures. In regard to these questions the results of in vestigations which have been made on roundoff errors in a more general context dealing with matrix inversion and eigenvalue problems could be used for the purposes of this paper. The emphasis of this investigation lay rather on studying the behavior of typical linear programming problems from the pOint of view of error cumulation.
