Linear Programming and Extensions

Linear Programming and Extensions. Instructor: Prof. Prabha Sharma, Department of Mathematics and Statistics, IIT Kanpur. The objective of this course is to introduce those real life problems which can be formulated as Linear Programming Problems (LPP). The course will be taught as a first course in optimization, hence all the concepts will be properly motivated and explained with examples. Topics covered in this course include Simplex algorithm; Duality theory and its ramifications; Basic ideas of the ellipsoid algorithm and Karmarkar's algorithm; Special cases of LPP; and Dynamic programming and PERT/CPM algorithms.
