Deterministic rounding of linear programs

WebJun 5, 2012 · In this chapter, we will look at one of the most straightforward uses of linear programming. Given an integer programming formulation of a problem, we can relax it to a linear program. We solve the linear program to obtain a fractional solution, then round … WebFifth step was determination of the probability values that will be input in the analysis. Sixth step was evaluation on the deterministic equivalent values of the probabilistic figures.
