In the pickup and delivery problem with time windows (PDPTW), vehicles have to transport loads from origins to destinations respecting capacity and time constraints. In this paper, we present a two-phase method to solve the PDPTW. In the first phase, we apply a novel construction heuris tics to generate an initial solution. In the second phase, a tabu search method is proposed to improve the so...

Introduction The essence of benchmarking is the process of identifying the highest standards of excellence for products, services, or processes, and then making the improvements necessary to reach those standards, commonly called " best practices ". The justification lies partly in the question: " Why re-invent the wheel if I can learn from someone who has already done it? " Jackson Grayson Jr,...

Regression benchmarking is a methodology for detecting performance changes in software by periodic benchmarking. Detecting performance regressions in particular helps to improve software quality, similarly as regression testing, which however focuses only on software functionality. To achieve an acceptable level of false alarms, regression benchmarking requires a statistically sound planning an...

Application speedups can be achieved by speeding up the hardware, e.g. by utilising an Operating System co-processor. The paper present results from a comparison of executing benchmark programs on a system with and without a coprocessor, but which otherwise are identical. The observed speedup is mostly due to the fact that there is no need for clock tick administration, in the system with co-pr...
