This course is devoted to the analysis of algorithms and combinatorial optimization problems in a probabilistic framework. A natural setting for the investigation of such problems is often provided by a (geometric) graph. For a given system (graph), the average or most likely behavior of an objective function of the system will be studied. In addition to asymptotic results, which describe a system as its size increases, quantitative laws for systems of fixed size will be described. Among the specific problems to be explored are
- the long-common-subsequence problem,
- packing problems,
- the Euclidean traveling salesman problem,
- minimal Euclidean matching,
- minimal Euclidean spanning tree.
For the analysis of problems of this type, several techniques and concepts have been developed and will be introduced and applied in this course. Some of these are
- concentration inequalities and concentration of measure,
- subadditivity and superadditivity,
- martingale methods,
