Discrete Ricci curvature formulations offer novel perspectives for characterizing geometric properties of weighted graphs. This work proposes continuous piecewise linear Ricci curvature flows and ...

Args: model (cp_model.CpModel): The constraint programming model. x (cp_model.IntVar): The input variable. f (PiecewiseLinearFunction): The piecewise linear function. upper_bound (bool): Flag ...

Each student had a different graph showing his position as a (piecewise-linear) function of time. From these we could get instantaneous velocities. Now let’s consider the reverse situation.

This paper considers a stochastic shortest path problem where the arc lengths are independent random variables following a normal distribution. In this problem, the optimal path is one that maximizes ...
