We study the total traveling distance minimization problem of the locker-based drone delivery (LDD), in which the roofs of the lockers are reused as parking platforms for drones such that the lockers and drones can work in a cooperative manner. It is a drone routing and parking hybrid problem...

Because of the clearly important role cooperative systems play in areas such as military sciences, biology, communications, robotics, and economics, just to name a few, the study of cooperative systems has intensified. This book provides an insight in the basic understanding of cooperative...

A simple measure of similarity for the construction of the market graph is proposed. The measure is based on the probability of the coincidence of the signs of the stock returns. This measure is robust, has a simple interpretation, is easy to calculate and can be used as measure of similarity...
