Hybrid CP+LNS for the Curriculum-Based Course Timetabling Problem
Course Timetabling (CTT) [11] is a popular combinatorial optimization problem, which deals with generating university timetables by scheduling weekly lectures, subject to conflicts and availability constraints, while minimizing costs related to resources and user discomfort. In CB-CTT, students enrol to curricula i.e., (possibly overlapping) collections of courses. Lectures of courses pertainin...
متن کاملSAT Model for the Curriculum-Based Course Timetabling Problem
Two widely used problems are the Satisfiability problem (SAT) and the Curriculum-Based Course Timetabling (CB-CTT) problem. The SAT problem searches for an assignment that make true a certain boolean formula. On the other side, the CB-CTT involves the task of scheduling lectures of courses to rooms, considering teacher availability, a specified curricula, and a set of constraints. Given the adv...
متن کاملHarmony Search Algorithm for Curriculum-Based Course Timetabling Problem
In this paper, harmony search algorithm is applied to curriculum-based course timetabling. The implementation, specifically the process of improvisation consists of memory consideration, random consideration and pitch adjustment. In memory consideration, the value of the course number for new solution was selected from all other course number located in the same column of the Harmony Memory. Th...

هدف پژوهش حاضر ارائه ی الگویی بر اساس کنش گفتار و کارکرد زبان برای تدوین مطالب درس "بررسی آثار ترجمه شده ی اسلامی" می باشد. در الگوی جدید، جهت تدوین مطالب بهتر و جذاب تر، بر خلاف کتاب-های موجود، از مدل های سطوح گفتارِ آستین (1962)، گروه بندی عملکردهای گفتارِ سرل (1976) و کارکرد زبانیِ هالیدی (1978) بهره جسته شده است. برای این منظور، 57 آیه ی شریفه، به صورت تصادفی از بخش-های مختلف قرآن انتخاب گردید...
15 صفحه اولFlow Formulations for Curriculum-based Course Timetabling
In this paper we present two mixed-integer programming formulations for the Curriculum based Course Timetabling Problem (CTT). We show that the formulations contain underlying network structures by dividing the CTT into two separate models and then connect the two models using flow formulation techniques. The first mixed-integer programming formulation is based on an underlying minimum cost flo...
