This research aims to produce an optimal college course schedule by reducing the number of conflicting courses and ensuring an even distribution of classes to ease the students' workload. To achieve this goal, schedule optimization uses a genetic algorithm. This algorithm is well-suited for solving large-scale and complex problems, such as college course scheduling that involves many variables and constraints. Local search techniques assist the genetic algorithm in improving performance and accelerating convergence. This research is expected to produce an optimal course schedule based on the criteria of minimizing course conflicts and evenly distributing classes to ease students' workload. The research results show that an optimal new schedule was successfully obtained."

Training institutions where individuals will be given special knowledge or training related to their respective fields have special characteristics and are not owned by the university, among others, training institutions focus on business needs. Accurate, precise and comprehensive scheduling is needed in a training institution, because of the increasing need for certain knowledge and skills that must be owned by every individual. Good scheduling will directly affect the improvement of quality of individuals in an institution or company. Efficient scheduling will be realized using a binary mathematical model. In this study, a development of a binary model was used to make a scheduling for leadership learning in a non-university training institution. This model optimizes scheduling so that it becomes more efficient. The model was developed based on problems in the field and solved using genetic algorithms with the Matlab programming language. This model provides each learning in the appropriate class. The genetic algorithm in this study can solve the problem of scheduling leadership classes by optimally meeting existing constraints."

"This book constitutes the thoroughly refereed post-proceedings of the 9th International Workshop on Approximation and Online Algorithms, WAOA 2011, held in Saarbrücken, Germany, in September 2011. The 21 papers presented were carefully reviewed and selected from 48 submissions. The volume also contains an extended abstract of the invited talk of Prof. Klaus Jansen. The Workshop on Approximation and Online Algorithms focuses on the design and analysis of algorithms for online and computationally hard problems. Both kinds of problems have a large number of applications in a wide variety of fields. Topics of interest for WAOA 2011 were: algorithmic game theory, approximation classes, coloring and partitioning, competitive analysis, computational finance, cuts and connectivity, geometric problems, inapproximability results, mechanism design, network design, packing and covering, paradigms for design and analysis of approximation and online algorithms, parameterized complexity, randomization techniques and scheduling problems."

"Penempatan posisi Access Point pada Jaringan Wifi.id yang tepat sangat diperlukan untuk mengoptimalkan kekuatan sinyal yang diterima dari transmitter ke receiver. Parameter yang paling mempengaruhi dalam menentukan performa posisi Access Point adalah nilai kekuatan sinyal, karena nilai inilah yang akan digunakan untuk menentukan coverage area (cakupan sinyal) dari sebuah transmitter (Access Point).Pada penelitan ini telah dilakukan pengukuran terhadap kekuatan sinyal access point terhadap penerima di ruang EBIS WITEL Yogyakarta yang diukur menggunakan InSSIDER dan dihasilkan RSSI (Receive Signal Strength Indicator) dari sebuah transmitter terhadap receiver. Dalam pengukuran juga digunakan propagasi Line Of Sight (LOS) dan propagasi Non Line Of Sight (NLOS). Data yang diperoleh dari hasil pengukuran dilapangan digunakan untuk melakukan pemodelan penempatan posisi Acces Point menggunakan metode algoritma genetika. Kekuatan sinyal RSSI yang diterima oleh receiver tidak hanya bergantung pada jarak antara transmitter dan receiver, akan tetapi menunjukkan variasi yang besar terhadap fading dan shadowing pada sebuah lokasi, juga pengaruh interferensi dapat menyebabkan penurunan sinyal (RSSI) yang diterima oleh receiver.Dari hasil penelitian yang dilakukan, diharapkan dapat menghasilkan pemodelan yang sesuai dan tepat guna dalam melakukan optimisasi penempatan posisi Access Point pada jaringan Wifi.Id menggunakan metode algoritma genetika.

Positioning of access point on wifi.id?s network on the right place is needed to optimize the signal strength received from the transmitter to the receiver . The parameters that most influence in determining the performance of the position of the access point is the value of the signal strength, because the value that will be used to determine the coverage area (signal coverage) of a transmitter (access point).

In this research has been done measuring the signal strength of the access point to the receiver in the room EBIS Witels Yogyakarta measured using inSSIDer and generated RSSI (Receive Signal Strength Indicator) from a transmitter to a receiver. Measurements were also used in the propagation of Line Of Sight (LOS) and propagation Non Line Of Sight (NLOS). Data obtained from field measurements are used for modeling the placement of the access point using genetic algorithm. RSSI signal strength received by the receiver does not only depend on the distance between transmitter and receiver, but showed a large variation against fading and shadowing at a location, also influence the interference can cause a decrease in the signal (RSSI) received by the receiver.

From the research conducted, is expected to generate appropriate modeling and effective in optimizing the placement of the access point on the wifi.id?s network using genetic algorithm."
