Approximation Algorithms for Combinatorial Optimization

In combinatorial optimization, the most important challenges are presented by problems belonging to the class NP-hard. For such problems no algorithm is known that can solve all instances in polynomial time. It is also strongly believed that no polynomial algorithm is capable of doing this. Although it is very difficult to solve exactly any of the NP-hard problems, some of them are amenable to ...

Fast Line Detection Algorithms Based on Combinatorial Optimization

In this paper we present a new class of algorithms for detecting lines in digital images. The approach is based on a general formulation of a combinatorial optimization problem. It aims at estimating piecewise linear models. A linear system is constructed with the coordinates of all contour points in the image as coefficients and the line parameters as unknowns. The resulting linear system is t...

CSC 5160 : Combinatorial Optimization and Approximation Algorithms

In this lecture, the focus is on submodular function in combinatorial optimizations. The first class of submodular functions which was studied thoroughly was the class of matroid rank functions. The flourishing stage of matroid theory came with Jack Edmonds’ work in 1960s, when he gave a minmax formula and an efficient algorithm to the matroid partition problem, from which the matroid intersect...

Approximation Algorithms for Reliable Stochastic Combinatorial Optimization

We consider optimization problems that can be formulated as minimizing the cost of a feasible solution wx over an arbitrary combinatorial feasible set F ⊂ {0, 1}n. For these problems we describe a broad class of corresponding stochastic problems where the cost vector W has independent random components, unknown at the time of solution. A natural and important objective that incorporates risk in...
