A University Timetabling Problem (UTP) belongs to NP-complete (Nondeterministic Polynomial-Complete) problem category since it has huge search space that consists of many students, classrooms, lectures, and courses permutation. Due to that, finding an optimal schedule using exact algorithm is impossible to be done under a reasonable time. Harmony Search is a heuristic method that can solve NP-Complete problem such as UTP in reasonable time. However because of its heuristic nature, it can only provide solution which is close to the perfect solution. Therefore, to prove that a schedule is a feasible solution, several constraints have to be satisfied. This research used Harmony Search to solve the UTP whereby the dataset, constraints, and experiments are acquired and performed in STMIK Mikroskil. This research also evaluates the speed performance and fitness value of Harmony Search using different parameter configuration. From its finding, the HMCR parameter value that is best suited f...

A hybrid metaheuristic approach to the university course timetabling problemThe university course timetable problem (UCTP) is known to be NP-hard, with solution complexity growing exponentially with the problem size. This paper introduces an algorithm that effectively tackles UCTPs by employing a combination of exploration and exploitation strategies. The algorithm comprises two main components. Firstly, it utilizes a genetic algorithm (GA) to explore the search space and discover a solution within the global optimum region. Secondly, it enhances the solution by exploiting the region using an iterated local search (ILS) algorithm. The algorithm is tested on two common variants of UCTP: the post-enrollment-based course timetable problem (PE-CTP) and the curriculum-based course timetable problem (CB-CTP). The computational results demonstrate that the proposed algorithm yields competitive outcomes when compared empirically against other existing algorithms. Furthermore, a t-test comparison with state-of-the-art algorithms is conducted. The experimental findin...
The university course timetabling problem is a combinatorial optimisation problem in which a set of events has to be scheduled in time slots and located in suitable rooms. The design of course timetables for academic institutions is a very difficult task because it is an NP-hard problem. This paper proposes a genetic algorithm with a guided search strategy and a local search technique for the university course timetabling problem. The guided search strategy is used to create offspring into the population based on a data structure that stores information extracted from previous good individuals. The local search technique is used to improve the quality of individuals. The proposed genetic algorithm is tested on a set of benchmark problems in comparison with a set of state-of-the-art methods from the literature. The experimental results show that the proposed genetic algorithm is able to produce promising results for the university course timetabling problem.

As a result of archaeological research conducted in the Southern Caucasus, including Azerbaijan, a number of settlements belonging to the Late Chalcolithic period were discovered. A research has shown that the Late Chalcolithic culture in Azerbaijan has its own characteristics, and the “Ovçular Tepe culture” and “Leyla Tepe culture” were formed here. But despite this, many of Caucasian scholar’s studies generally named the Late Chalcolithic culture of the Southern Caucasus sometimes the Sioni Culture, sometimes Sioni-Tsopi Culture, sometimes Sioni ceramics, and sometimes Sioni-type monuments in textbooks. Recently, this culture has been named the Sioni-Tsopi-Ginchi Culture. According to all these facts it can be said that the Sioni Culture has become the synonym of the Late Chalcolithic culture of the Southern Caucasus. The investigation of Late Chalcolithic monuments located in the Southern Caucasus shows that they differ from each other in terms of their architecture and ceramics. The period and characteristic features of the Sioni Culture also are not fully defined. Ceramics belonging to the second group in the Tumbul Tepe settlement are similar to Sioni ceramics in some of their characteristics. However, researches show that this type of ceramics was not a separate culture, but a part of the Late Chalcolithic culture. We believe that the reason for such diversity of ceramics is related to their functional purpose. Even if it is possible to call a group of Late Chalcolithic monuments in the Southern Caucasus the Sioni-Tsopi-Ginchi Culture, it is not correct, in our opinion, to attribute this to all the monuments of the Southern Caucasus. It should be noted that this type of ceramics, distributed in different periods and monuments of different characteristics, differs from each other due to local characteristics. This shows that they do not spread from one center.

This book brings together the insights of twenty-six scholars across eighteen articles, and it delves into key themes of Cistercian Studies, including the normative frameworks, visitations, and reforms within the Cistercian Order. It explores the distinctiveness of specific communities, the interplay between Cistercian architecture and liturgical texts and practises, and the significance of Iberian Cistercian libraries and manuscripts. The book also examines the material characteristics and technical evolution of the Cistercian Order using advanced laboratory techniques, providing crucial contributions to the history of the Alcobaça scriptorium in its early centuries and continuing to influence Cistercian studies today.

تجسد سلسلة الاحداث والاضطرابات الداخلية والخارجية التي عصفت بالمشهد الاسرائيلي خلال 2023 وعلى رأسها حركة الاحتجاج المناهضة لخطة الإصلاح القضائي وهجوم حماس المباغت في 7 أكتوبر وما تمخض عنه من حرب إبادة على غزة ،الأزمة العضوية التي وصلتها إسرائيل رغم مرور 76 عاما على اقامتها وفشلها في تجاوز مسألتين حارقتين : أولًا حسم الصراع مع السكان الاصلانيين (الفلسطينيين)؛ وثانيًا إقامة رؤية قومية جامعة قادرة على احتواء تناقضات الجماعات المتنوعة التي أفرزها تطور مجتمع المهاجرين. وهو ما يعني ان هذه الازمة بتعبيراتها المتفاوتة الداخلية والخارجية وفي ظل استمرار الشروط البنيوية التي أفرزتها، وانضفارها ببنية المشروع الصهيوني الاستعماري-استيطاني وتطوره الجدلي وصفرية فرص التغيير الداخلي، يمكن ان تتم ادارتها وتسكينها فقط على أساس تسويات مؤقتة تظل هشة وقابلة للانهيار في أي لحظة، ما يعني ان الازمة تظل مؤهلة للتصاعد والتفجر من جديد وبعنف اكبر اذا لم يتم معالجة أسبابها البنيوية.
