متن کاملProfit-maximizing pricing for tollbooths
The input to the tollbooth problem is a graph G = (V,E) and a set of m buyers Pi where each buyer is interested in buying a path Pi connecting si, ti ∈ V . Each buyer comes with a budget b(Pi), a positive real number. The problem is to set non-negative prices to the edges E of G. A buyer buys her path Pi if the sum of prices on Pi is at most her budget. If a buyer buys her path, we obtain a pro...
