چکیده

NP-complete decision problems are one of the most important subjects in computer science. We have developed a knowledge base of NP-complete decision problems that reflects the conceptual knowledge and the relationships of more than 350 decision problems including additional information resources such as bibliographic references or author information. The knowledge base is applied by the web based bibliographic search tool NPBibSearch. By providing an intuitive graphical user interface for navigation within the domain of NP-complete decision problems and by integrating full text search capabilities with conceptual knowledge, NPBibSearch offers the user an ontology augmented bibliographic search.

Reasoning with Ordered Binary Decision Diagrams

We consider problems of reasoning with a knowledge-base, which is represented by an ordered binary decision diagram, for two cases of general and Horn knowledge-bases. Our main results say that both 2nding a model of a knowledge-base and deducing from a knowledge-base can be done in linear time for a general knowledge-base, but that abduction is NP-complete even for a Horn knowledge-base. Then,...

Developing a Permutation Method Using Tabu Search Algorithm: A Case Study of Ranking Some Countries of West Asia and North Africa Based on Important Development Criteria

The recent years have witnessed an increasing attention to the methods of multiple attribute decision making in solving the problems of the real world due to their shorter time of calculation and easy application. One of these methods is the ‘permutation method’ which has a strong logic in connection with ranking issues, but when the number of alternatives increases, solving problems through th...

A heuristic approach for multi-stage sequence-dependent group scheduling problems

We present several heuristic algorithms based on tabu search for solving the multi-stage sequence-dependent group scheduling (SDGS) problem by considering minimization of makespan as the criterion. As the problem is recognized to be strongly NP-hard, several meta (tabu) search-based solution algorithms are developed to efficiently solve industry-size problem instances. Also, two different initi...

A Tabu Search Method for a New Bi-Objective Open Shop Scheduling Problem by a Fuzzy Multi-Objective Decision Making Approach (RESEARCH NOTE)

This paper proposes a novel, bi-objective mixed-integer mathematical programming for an open shop scheduling problem (OSSP) that minimizes the mean tardiness and the mean completion time. To obtain the efficient (Pareto-optimal) solutions, a fuzzy multi-objective decision making (fuzzy MODM) approach is applied. By the use of this approach, the related auxiliary single objective formulation can...
