A Bi-criteria Hybrid Genetic Algorithm with Robustness Objective for the Course Timetabling Problem
Akkan, Can; Gülcü, Ayla (Elsevier, 2018)Traditional methods of generating timetables may yield high-quality solutions, but they may not yield robust solutions that may easily be adapted to changing inputs. Incorporating late changes by making minimum modifications ... -
Clustering Electricity Market Participants Via FRM Models
Gülcü, Ayla; Çalışkan, Sedrettin (IOS Press, 2020)Collateral mechanism in the Electricity Market ensures the payments are executed on a timely manner; thus maintains the continuous cash flow. In order to value collaterals, Takasbank, the authorized central settlement ... -
Integer Programming Versus Constraint Programming: a Course Timetabling Case Study
Gülcü, Ayla; Bulkan, Serol (University of Cincinnati Industrial Engineering, 2019)In this study, two solution approaches are compared for a real-world, moderate-size but a highly constrained university course timetabling problem. The first approach is developing an integer programming model and solving ... -
Minimum Penalty Perturbation Heuristics for Curriculum-Based Timetables Subject to Multiple Disruptions
Akkan, Can; Gülcü, Ayla; Kuş, Zeki (Elsevier, 2021)Course timetables are often rendered infeasible due to unexpected changes in requirements and must be repaired. Given an initial timetable, planners prefer a repaired timetable whose quality is worsened as little as possible ... -
Robust University Course Timetabling Problem Subject to Single and Multiple Disruptions
Gülcü, Ayla; Akkan, Can (Elsevier, 2020)University course timetables are often finalized in stages, in between which, changes in the data make the earlier version infeasible. As each version is announced to the community, it is desirable to have a robust initial ... -
Search Space Sampling by Simulated Annealing for Identifying Robust Solutions in Course Timetabling
Akkan, Can; Gülcü, Ayla; Kuş, Zeki (Institute of Electrical and Electronics Engineers Inc., 2020)For many combinatorial optimization problems, it is important to identify solutions that can be repaired without degrading solution quality in case changes in the data associated with the constraints make the initial ... -
Veri Madenciliği Teknikleriyle Türkçe Web Sayfalarının Kategorize Edilmesi
Şekerci Hüsem, Seçil; Gülcü, Ayla (IEEE, 2017)Günümüzde artan veri miktarıyla başa çıkabilmek için tek başına insan gücünün kullanılması mümkün görünmemektedir. Bu sebeple benzer dokümanları bir araya gruplayabilecek ya da dokümanları, önceden tanımlı kategorilere ...
