The telecommunications industry is greatly concerned about customer churn due to dissatisfaction with service. This has started investing in the development of machine learning (ML) models for prediction extract, examine and visualize their customers’ historical information from a vast amount big data which will assist further understand needs take appropriate actions control churn. However, hi...

A shortest path search method based on ant colony algorithm is proposed. The method contracts the search space appropriately, obtaining, in a short time, a path that is as close as possible to the path obtained by the Dijkstra method (the optimum path). To improve the performance, we modify the pheromone update rule and introduce a learning strategy into the ant colony algorithm. The method obt...

A new population-based search algorithm called the Bees Algorithm (BA) is presented in this paper. The algorithm mimics the food foraging behavior of swarms of honey bees. This algorithm performs a kind of neighborhood search combined with random search and can be used for both combinatorial optimization and functional optimization and with good numerical optimization results. ABC is a meta-heu...

In recent years, Japan, and especially rural areas have faced the growing problems of debt-ridden local railway lines along with population decline aging population. Therefore, it is best to consider discontinuation introduce replacement buses secure transportation methods people in areas. Based on above background, targeting that may be discontinued near future, appropriate bus stops when prov...

A combinatorial auction is an auction where the bidders have the choice to bid on bundles of items. The WDP in combinatorial auctions is the problem of finding winning bids that maximize the auctioneer’s revenue under the constraint that each item can be allocated to at most one bidder. The WDP is known as an NP-hard problem with practical applications like electronic commerce, production manag...
