Heuristic Backbone Sampling for Maximum Satisfiablity
- …The weighted maximum satisfiability (MAXSAT) problem is of great interest to the Artificial Intelligence community, as a model for several constraint satisfaction problems (emerging e.g. from planning) which require that an optimum subset of their constraints be satisfied.…

A generic object-oriented constraint-based model for university course timetabling
- …Abstract. The construction of course timetables for academic institutions is a very difficult problem with a lot of constraints that have to be respected and a huge search space to be explored, even if the size of the problem input is not significantly large, due to the exponential number of the pos…

Logic as Vehicle for Real Life Applications
- …Real life applications involve entities and algorithms that are complex to model and implement. Logic programming, the most practical approach of logic, facilitates the development procedure for these applications. However, its declarativeness does not seem sufficient to provide the means for the…

Integrating Direct CP Search and CP-based Column Generation for the Airline Crew Assignment Problem
- …. We introduce a hybrid approach integrating CP-based Column Generation and pure CP methods. It is being applied to the large scale optimization problem of Airline Crew Assignment. The combination of methods from CP and OR results in an algorithm that overcomes the inherent weaknesses of each ap…

A Tour Advisory System Using A Logic Programming Approach
- …A PErsonalized Tourist INformation Advisor is presented, called PETINA, which is a system aiming at constructing tours that satisfy constraints specified by tourists. The system consults a database which contains information about activities, events and sites that refer to Greece. PETINA takes as in…

Construction and Repair: A Hybrid Approach to Search in CSPs
- …In order to obtain a solution to a constraint satisfaction problem, constructive methods iteratively extend a consistent partial assignment until all problem variables are instantiated. If the current partial assignment is proved to be inconsistent, it is then necessary to backtrack and perform alte…

UTSE: Construction of Optimum Timetables for University Courses - A CLP Based Approach
- …The construction of timetables for universities or schools is an extremely complex problem, whose manual solution requires much effort. The set of all possible solutions, that is the search space of the problem, is very large, at least in the realworld examples. An acceptable solution is one that sa…

Summarization from medical documents: A survey
- …Objective: The aim of this paper is to survey the recent work in medical documents summarization. Background: During the last decade, documents summarization got increasing attention by the AI research community. More recently it also attracted the interest of the medical research community as well,…

Combinatorial Optimization through Statistical Instance-Based Learning
- …Different successful heuristic approaches have been proposed for solving combinatorial optimization problems. Commonly, each of them is specialized to serve a different purpose or address specific difficulties. However, most combinatorial problems that model real world applications have a priori wel…
