Abstract

This paper is on the enhancement of our heuristics for GOSST problem that could apply to the design of communication networks offering graduated services. This problem hewn as one of NP-Hard problems finds a network topology meeting the G-Condition with minimum construction cost. In our prior research, we proposed two heuristics. We suggest methods of selecting G-Node and disconnections for Global or Local locating heuristic in this research. The ameliorated Local locating heuristic retrenches 17% more network construction cost saving ratio and the reformed Global locating heuristic does 14% more than our primitives.

GOSST 문제에 대한 이전 휴리스틱의 성능 개선을 위한 새로운 제안이 본 논문에서 제시된다. 이 문제는 다양한 등급의 서비스를 제공할 수 있는 통신 네트워크의 설계 등에 적용될 수 있다. GOSST 문제는 G-Condition을 만족하는 최소 구축비용의 네트워크를 찾는 것으로 NP-HARD 문제에 포함된다. 우리는 이전의 연구에서 이 문제와 관련된 두개의 휴리스틱을 발표하였다. 본 연구에서는 스타이너 트리 생성 시 이용되는 G-Node와 제거되는 에지의 선택 방법을 제안하고, 이를 기존의 휴리스틱에 접목한 새로운 휴리스틱을 구현한다. 실험 결과는 이 휴리스틱이 이전 것에 비해 우수함을 나타내는데, 새 지역적 배치 휴리스틱은 17%, 새 전역적 배치 휴리스틱은 14%의 네트워크 구축비용 절감비율의 증가를 보였다.
