A network induced by wealth is a social network model in which wealth induces individuals to participate as nodes, and every node in the network produces and accumulates wealth utilizing its links. More specifically, at every time step a new node is added to the network, and a link is created between one of the existing nodes and the new node. Innate wealthproducing ability is randomly assigned...

With reference to the discussion about shareholder versus stakeholder maximization it is argued that the normal type of maximization is in fact stakeholder-owner maximization. This means maximization of the sum of the value of the shares and stakeholder benefits belonging to the dominating stakeholder-owner. Maximization of shareholder value is a special case of owner-maximization, and only und...

Adaptive submodular maximization has been extensively studied in the literature. However, most of existing studies this field focus on pool-based setting, where one is allowed to pick items any order, and there have few for stream-based setting arrive an arbitrary order must immediately decide whether select item or not upon its arrival. In paper, we introduce a new class utility functions, sem...

We consider the problem of maximizing a non-negative monotone submodular function subject to knapsack constraint, which is also known as Budgeted Submodular Maximization (BSM) problem. Sviridenko (Operat Res Lett 32:41–43, 2004) showed that by guessing 3 appropriate elements an optimal solution, and then executing greedy algorithm, one can obtain approximation ratio $$\alpha =1-{1}/{e} \approx ...
