Parametric Integer Programming: The Right-Hand-Side-Case

A family of integer programs is considered whose right-hand-sides lie on a given line segment L. This family is called a parametric integer program(PIP). Solving a (PIP) means finding an optimal solution for every program in the family. It is shown how a simple generalization of the conventional branch-and-bound approach to integer programming makes it possible to solve such a (PIP). The usual bounding test is extended from a comparison of two point values to a comparison of two functions defined on the line segment L. The method is illustrated on a small example and computational results for some larger problems are reported.Supported in part by the U.S. Army Research Office (Durham) under Contract DAHC04-73-C-0032

THe Use of the Box Step Method in Discrete Optimization

The Boxstep method is used to maximize Lagrangean functions in the context of a branch-and-bound algorithm for the general discrete optimization problem. Results are presented for three applications: facility location, multi-item production scheduling, and single machine scheduling. The performance of the Boxstep method is contrasted with that of the subgradient optimization method.

FROM YOU I GET THE STORY: Tracking spirituality through the three iterations of The Who’s Tommy

In the late 1960s, Pete Townshend, lead guitarist and composer for British rock band The Who, discovered the teachings of Indian spiritual leader Meher Baba. Inspired by these teachings he wrote the concept album for the first successful rock opera: Tommy. The smashing success of this album led to its adaptation into a major Hollywood film directed by Ken Russell in 1975 and its adaptation into a Broadway musical directed by Des McAnuff in 1992. This thesis examines how each adaptation contributes to the Westernization, generalization, and sanitization of the spirituality inherent to the original concept album as well as how these adaptations reflect the conflicting objectives of their lead artists

YANG MENANGIS DI BALIK PELAMINAN KARYA ALDA MUHSI: PANDANGAN DAN NILAI PERNIKAHAN ADAT DALAM CERPEN

Marriage is a part of the human life cycle that plays an important role in various aspects of human life.Marriage can be seen as something important because it contains values. Marriage can be seen as a social institution, so marriage regulates relationships between individuals in determining their respective roles and responsibilities. In many Indonesian literary works, you can find images ofmarriage. This research uses the short story Yang Menangis di Balik Pelaminan by Alda Muhsi toexamine the views of the characters and the value of traditional marriage contained in the short story. The short story is analyzed using literary sociology to see the phenomenon of traditional marriage and its value. This research found that there were differences in the views of figures regarding traditional marriage. There are views of figures who state the importance of traditional marriages and there are also views which believe that traditional marriages no longer need to be implemented. This is because times have changed. The result of the next discussion is regarding the value of traditional marriage inshort stories. There are three values in traditional marriage, namely, value in terms of human needs,value in terms of human ability to capture and develop it, value seen from cultural processes.Pernikahan merupakan salah satu bagian dari daur hidup manusia yang memegang peranan penting dalam berbagai aspek kehidupan manusia. Pernikahan dapat dilihat sebagai sesuatu yang penting karena di dalamnya terdapat nilai-nilai. Pernikahan dapat dilihat sebagai suatu institusi sosial, maka pernikahan mengatur hubungan antar individu dalam menentukan peran dan tanggung-jawabmasing-masing. Dalam banyak karya sastra Indonesia dapat ditemukan gambaran pernikahan. Penelitian ini mengambil cerpen Yang Menangis di Balik Pelaminan karya Alda Muhsi untuk diteliti pandangan tokoh dan nilai pernikahan adat yang terkandung di dalam cerpen. Cerpen dianalisis dengan sosiologi sastra untuk melihat fenomena pernikahan adat dan nilainya. Penelitian ini menemukan adanya perbedaan pandangan tokoh-tokoh mengenai pernikahan adat. terdapat pandangan tokoh yang menyatakan pentingnya pernikahan adat dan terdapat pandangan pula pandangan yang menganggap bahwa pernikahan secara adat tidak perlu lagi dilaksanakan. Hal tersebut didasari bahwa zaman telah berubah. Hasil pembahasan selanjutnya adalah mengenai nilai pernikahan adat di dalam cerpen. Terdapat tiga nilai di dalam pernikahan adat, yaitu, nilai dari segi kebutuhan manusia, nilai dari segi kemampuan manusia untuk menangkap dan mengembangkannya, nilai dilihat dari proses budaya

Pengelolaan Lingkungan Pesisir Melalui Aksi Bersih Sampah Sebagai Upaya Konservasi di Wisata Pantai Putih Kabupaten Manokwari, Papua Barat

Pantai Pasir Putih di Kabupaten Manokwari, Papua Barat adalah tujuan wisata alam yang menarik dengan pasir lembut, air jernih, dan pemandangan alam yang memukau, menarik minat wisatawan baik lokal maupun internasional. Namun, pesona alamnya terusik oleh permasalahan serius, yaitu keberadaan sampah di tepi pantai, terutama sampah plastik seperti botol, kantong, dan wadah makanan sekali pakai yang sering berserakan di sekitar pantai. Penting untuk mengelola sampah di pantai dengan tindakan khusus, termasuk program pembersihan rutin, meningkatkan kesadaran masyarakat, dan melakukan kampanye pendidikan lingkungan. Tujuan utama dari kegiatan ini adalah meningkatkan kesadaran dan tanggung jawab pelajar, masyarakat, dan wisatawan dalam menjaga lingkungan pesisir di Kabupaten Manokwari, khususnya di Wisata Pantai Putih. Kegiatan pengabdian kepada masyarakat ini diadakan di Wisata Pantai Pasir Putih, Kabupaten Manokwari, Papua Barat. Acara tersebut dilakukan pada hari Minggu, 3 Juni 2023, dan mencakup tahapan sosialisasi rencana, koordinasi, dan pelaksanaan kegiatan untuk mencapai tujuan yang telah ditetapkan. Program pengabdian menunjukkan komitmen kuat dalam menjaga keindahan Pantai Putih. Melibatkan mahasiswa sastra Indonesia dan Inggris membawa perspektif kaya tentang isu lingkungan. Keberhasilan kegiatan mencerminkan sinergi edukasi, kesadaran masyarakat, dan aksi nyata menjaga lingkungan pesisir. Kabupaten Manokwari jadi contoh perlindungan lingkungan, diharapkan masyarakat bertanggung jawab terhadap alam. Program ini membuka pintu perubahan positif dan harmoni antara manusia dan alam

A hybrid approach to discrete mathematical programming

The dynamic programming and branch-and-bound approaches are combined to produce a hybrid algorithm for separable discrete mathematical programs. The hybrid algorithm uses linear programming in a novel way to compute bounds and is readily extended to solve a family of parametric integer programs with related right-hand-sides. Computational experience is reported on a number of linear and nonlinear integer programs.Supported in part by the U.S. Army Research Office (Durham) under Contract DAHC04-73-C-0032
