Support vector machine (SVM) algorithms were introduced to analyze the quality of seawater, and two models were constructed to analyze different seawater qualities, one is the SVM model for recognizing two kinds of seawater and the other is hierarchical support vector machines (H-SVMs) model for recognizing multi-seawater. The decision function of the first model for recognizing two kinds of seawater...
This paper studies a durable equipment-rental problem. Other than the classical ski-rental problem (Karp 1992), we assume that the decision-maker can sell the used equipment after paying a transaction cost when he no longer needs it. We find that the optimal opportunity of online algorithm with considering the profit selling used equipment is different from that of online algorithm without considering...
