Mechanism Design for Locating a Bridge Between Regions with Prelocated Facilities

Genjie Qin, Chenhao Wang, Jianan Lin +2

In many urban planning projects, social planners require the construction of a bridge to connect two regions separated by obstacles such as rivers or highways. This paper studies t…

Strategyproof Mechanisms for Euclidean Facility Location Problems under -norm Social Cost

Hau Chan, Jianan Lin, Chenhao Wang

We study strategyproof mechanisms for eliciting agents' location preferences truthfully in the Euclidean plane and locating a facility so as to minimize the -nor…

Mechanism Design for Connecting Regions Under Disruptions

Hau Chan, Jianan Lin, Zining Qin +1

Man-made and natural disruptions such as planned constructions on roads, suspensions of bridges, and blocked roads by trees/mudslides/floods can often create obstacles that separat…

Strategyproof Facility Location with Prediction: Minimizing the Maximum Cost

Hau Chan, Jianan Lin, Chenhao Wang

We study the mechanism design problem of facility location on a metric space in the learning-augmented framework, where mechanisms have access to imperfect predictions of the optim…

Obnoxious Facility Location Problems: Strategyproof Mechanisms Optimizing -Aggregated Utilities and Costs

Hau Chan, Jianan Lin, Chenhao Wang

We study the problem of locating a single obnoxious facility on the normalized line segment with strategic agents from a mechanism design perspective. Each agent has a pref…

A 1/2-Approximation for Budgeted -Submodular Maximization

Chenhao Wang

A -submodular function naturally generalizes submodular functions by taking as input disjoint subsets, rather than a single subset. Unlike standard submodular maximization,…
