Profile Likelihood via Optimisation and Differential Equations Open
Profile likelihood provides a general framework to infer on a scalar parameter of a statistical model. A confidence interval is obtained by numerically finding the two abscissas where the profile log-likelihood curve intersects an horizont…

Group Kernels for Gaussian Process Metamodels with Categorical Inputs Open
Gaussian processes (GP) are widely used as a metamodel for emulating time-consuming computer codes. We focus on problems involving categorical inputs, with a potentially large number L of levels (typically several tens), partitioned in G <…

Progressive Focus Search for the Static and Stochastic VRPTW with both Random Customers and Reveal Times Open
Static stochastic VRPs aim at modeling real-life VRPs by considering uncertainty on data. In particular, the SS-VRPTW-CR considers stochastic customers with time windows and does not make any assumption on their reveal times, which are sto…

Robustly disjoint paths with segment routing Open
Motivated by conversations with operators and by possibilities to unlock future Internet-based applications, we study how to enable Internet Service Providers (ISPs) to reliably offer connectivity through disjoint paths as an advanced, val…

The Static and Stochastic VRPTW with both random Customers and Reveal Times: algorithms and recourse strategies Open
Unlike its deterministic counterpart, static and stochastic vehicle routing problems (SS-VRP) aim at modeling and solving real-life operational problems by considering uncertainty on data. We consider the SS-VRPTW-CR introduced in Saint-Gu…

Automatic Synthesis of Smart Table Constraints by Abstraction of Table Constraints Open
The smart table constraint represents a powerful modeling tool that has been recently introduced. This constraint allows the user to represent compactly a number of well-known (global) constraints and more generally any arbitrarily structu…

On the validity of parametric block correlation matrices with constant within and between group correlations Open
We consider the set Bp of parametric block correlation matrices with p blocks of various (and possibly different) sizes, whose diagonal blocks are compound symmetry (CS) correlation matrices and off-diagonal blocks are constant matrices. S…
