We study the efficiency of mechanisms for allocating a divisible resource. Given scalar signals submitted by all users, such mechanism decides fraction resource that each user will receive and payment be collected from her. Users are self-interested aim to maximize their utility (defined as value they minus payment). Starting with seminal work Johari Tsitsiklis, long list papers studied price a...

Attracted by the inherent security and privacy protection of blockchain, incorporating blockchain into Internet Things (IoT) has been widely studied in these years. However, mining process requires high computational power, which prevents IoT devices from directly participating construction. For this reason, edge computing service is introduced to help build where could purchase resources serve...

Many portfolio optimization problems deal with allocation of assets which carry a relatively high market price. Therefore, it is necessary to determine the integer value of assets when we deal with portfolio optimization. In addition, one of the main concerns with most portfolio optimization is associated with the type of constraints considered in different models. In many cases, the resulted p...
