NettetLinear Programming. Macmillan, 1983 Modeling Linear programming is a flexible technique that can be applied to many real-world problems. A major advantage of modeling a prob-lem as an LP is that linear programs are efficiently solvable. That is, the computation time of an LP is polynomial9 in the number of 9 In complexity theory we … NettetThe various types of problem in linear programming problem included in class 12 concepts. They are: (i) Manufacturing problem- Here we maximize the profit with the help of minimum utilization of the resource. (ii) Diet Problem- We determine the number of different nutrients in a diet to minimize the cost of manufacturing.

All constraints in a linear program are convex (if x, y satisfy the constraints, then t x + ( 1 − t) y also does for all 0 ≤ t ≤ 1 ). The constraint a + b > 3 is not convex, since ( 4, 0) and ( − 4, 0) are both solutions while ( 0, 0) is not.
