The Temporary-Ordered Routing Algorithm (TORA) – An Operations Research Software
TORA is an algorithm i.e. a mathematical set of instructions or programs (mathematical-software). It is an optimization system in the area of operations research which is very easy to use. Further, TORA is menu-driven and Windows-based which makes it very user friendly.

The software has in-built tutorial for the novice and it also produces animated graphical linear programming solution. The other features of the software include dynamic construction of ‘Critical Path Method’ charts and creation of search-trees to name some.
The software can be executed in automated or tutorial mode. The automated mode reports the final solution of the problem, usually in the standard format followed in commercial packages, while the tutorial mode keeps on giving step-wise information about the methodology and solution.
TORA also offers self-paced learning of all the computational algorithms in a manner that allows students to check their understanding of the material with immediate detailed feedback from the software. It enables the instructors to demonstrate ideas that otherwise are literally impossible to present.
