Parallel Branch and Bound and Anomalies
نویسنده
چکیده
In this paper we present a classification of parallel branch and bound algorithms and investigate the anomalies which can occur during the execution of such algorithms. We develop sufficient conditions to prevent deceleration anomalies from degrading the performance. Such conditions were already known for some synchronous cases. It turns out that these conditions can be generalized to arbitrary cases. Finally we develop necessary conditions for acceleration anomalies to improve upon the performance. 1980 Mathematical Subject Classification: 90C27, 68Q10, 68R05.

How to Cope With Anomalies in Parallel Approximate Branch-and-Bound Algorithms
A genera! technique for solving a wide variety of search problems is the branch-and-bound (B&B) algorithm. We have adapted and extended B&B algorithms for parallel processing. Anomalies owing to parallelism may occur. -In this paper sufficient conditions to guarantee that parallelism will not degrade the performance are presented. Necessary conditions for allowi& parallelism to have a speedup g...
متن کاملPerformances of Parallel Branch and Bound Algorithms with Best-first Search
This paper analyzes the performances of parallel branch and bound algorithm with best-first search strategy by examining various anomalies on the expected speed-up: detrimental, acceleration and detrimental acceleration. Since the best evaluation is not always sufficient to distinguish the best node to choose with best-first search strategy, we define tie breaking rules for cases when nodes hav...
متن کاملA Novel B and B Algorithm for a Unrelated Parallel Machine Scheduling Problem to Minimize the Total Weighted Tardiness
This paper presents a scheduling problem with unrelated parallel machines and sequencedependent setup times that minimizes the total weighted tardiness. A new branch-and-bound (B and B) algorithm is designed incorporating the lower and upper bounding schemes and several dominance properties. The lower and upper bounds are derived through an assignment problem and the composite dispatching rule ...
متن کاملAsynchronous Parallel Branch and Bound and Anomalies
The parallel execution of branch and bound algorithms can result in seemingly unreasonable speedups or slowdowns. Almost never the speedup is equal to the increase in computing power. For synchronous parallel branch and bound, these effects have been studied extensively. For asynchronousparallelizations, only little is known. In this paper, we derive sufficient conditions to guarantee that an a...
متن کاملParallel Branch and Bound on an MIMD System
In this paper we give a classification of parallel branch and bound algorithms and develop a class of asynchronous branch and bound algorithms for execution on an MIMD system. We develop sufficient conditions to prevent the anomalies that can occur due to the parallelism, the asynchronicity or the nondeterminism, from degrading the performance of the algorithm. Such conditions were known alread...
