Abstract

Masalah knapsack merupakan masalah program bilangan bulat yang melibatkan satu kendala saja. Masalah knapsack umumnya diilustrasikan dengan suatu tas dan barang. Masalah yang akan kita selesaikan dalam masalah knapsack adalah memaksimumkan harga barang dengan kapasitas tertentu yang dapat dimuat oleh tas dengan kapasitas tertentu juga. Dalam menyelesaikan masalah knapsack, umumnya dapat dikerjakan secara langsung (penerkaan), menggunakan metode branch and bound, dan enumerasi implisit. Pada paper ini, akan dilakukan perbandingan penyelesaian masalah knapsack dengan metode branch and bound dan enumerasi implisit. Kita juga akan dapat melihat metode mana yang paling efektif untuk menyelesaikan suatu masalah knapsack.

Abstract

In the study of algebraic structures, the basic object of mathematics, namely sets, can be given abstract structures such as groups or rings. In this paper, we will study the algebraic structure found in crosses between two individuals with blood groups using the ABO, Rhesus, and MN systems.

Abstract

The concept of rough set was first introduced by Pawlak in 1982. The basic concepts in set theory such as intersections, unions, differences, and complements still apply to rough sets. Furthermore, researchers in the field of mathematics and informatics who study rough sets can relate the concept of rough sets to algebraic structures so that a concept called rough algebraic structures is obtained. Some concepts on rough algebraic structures are rough groups, rough rings, and rough modules. In this paper, the properties related to the ideal of roughness will be given to the rough ring.
