Approximation Solutions for Time-Varying Shortest Path Problem

Abstract. Time-varying network optimization problems have tradition-ally been solved by specialized algorithms. These algorithms have NP-complement time complexity. This paper considers the time-varying short-est path problem, in which can be optimally solved in O(T(m + n)) time,where T is a given integer. For this problem with arbitrary waiting times,we propose an approximation algorithm, whic...

Application of Information and Communication Technology for Dissemination of Agricultural Information among Farmers: Challenges and Opportunities

Agriculture is the backbone of India’s economy as two-third of the population live in rural areas and directly or indirectly depend on agriculture for their livelihood. India’s food production has improved significantly during the last three decades due to all-round efforts but Indian agriculture is still facing a multitude of problems to maximize productivity to feed the continuously increasin...

Minimizing a General Penalty Function on a Single Machine via Developing Approximation Algorithms and FPTASs

This paper addresses the Tardy/Lost penalty minimization on a single machine. According to this penalty criterion, if the tardiness of a job exceeds a predefined value, the job will be lost and penalized by a fixed value. Besides its application in real world problems, Tardy/Lost measure is a general form for popular objective functions like weighted tardiness, late work and tardiness with reje...
