Zusammenfassung: | Abstract: "The solution of difficult real world optimization problems usually requires far more computational power than offered by todays [sic] fastest computer. However, several computers may work in parallel on the solution of one single problem. Hereby, a way of increasing computational power is created, which scales with advances in hardware, i.e. if processors become 10 times faster, so will execution times for systems built by a number of these processors. If the solution algorithms for the problems in question are well designed, also solution times for these will then decrease by a factor 10. Branch and Bound (B & B) is by far the most widely used tool for solving large scale hard combinatorial optimization problems, and the combination of parallel computing and B & B has now for a number of years been studied in connection with different applications to derive principles for design of efficient parallel B & B algorithms. In this paper I briefly review the principles of sequential B & B and sketch the main trends in parallel Branch and Bound and the problems experienced. Based on personal experiences with parallel B & B over the last 5 years, I then give my view on the applicability of parallel B & B -- where do [sic] one find the large advantages, and which are the ideas to be exploited and pitfalls to be avoided when using parallel B & B in practical problem solving." |
