Distribution Network Reconfiguration: A Disjunctive Convex Hull Approach

IEEE Transactions on Power Systems, 2023
This letter theoretically reformulates the distribution network reconfiguration (DNR) model using the disjunctive convex hull approach. Continuous parent-child relationship variables in spanning tree constraints can be regarded as disjunctive variables ...

Beyond Bounding-Box: Convex-hull Feature Adaptation for Oriented and Densely Packed Object Detection

Computer Vision and Pattern Recognition, 2021
Detecting oriented and densely packed objects remains challenging for spatial feature aliasing caused by the intersection of reception fields between objects.

Between steps: Intermediate relaxations between big-M and convex hull formulations

Integration of AI and OR Techniques in Constraint Programming, 2021
This work develops a class of relaxations in between the big-M and convex hull formulations of disjunctions, drawing advantages from both. The proposed "P-split" formulations split convex additively separable constraints into P partitions and form the ...

Reducing Redundancy of Musculoskeletal Robot With Convex Hull Vertexes Selection

IEEE Transactions on Cognitive and Developmental Systems, 2020
It has been a long-term dream of roboticist to create a robot that has similar behavior and appearance to human. With highly redundant joints and actuators, the musculoskeletal system of human can fulfill movement and operation with high precision ...

Data-Driven Wind Generation Admissibility Assessment of Integrated Electric-Heat Systems: A Dynamic Convex Hull-Based Approach

IEEE Transactions on Smart Grid, 2020
This paper proposes a data-driven approach to assess the wind generation accommodation capability of the integrated electric-heat system. The overall assessment model is constructed based on the two-stage robust decision-making framework, where the ...

One-Class Convex Hull-Based Algorithm for Classification in Distributed Environments

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2020
In this paper, a new one-class classification algorithm capable of working in distributed environments is presented. In it, convex hull is used to build the boundary of the target class defining the one-class problem in each of the distributed nodes ...

Convex Hull Based Robust Security Region for Electricity-Gas Integrated Energy Systems

IEEE Transactions on Power Systems, 2019
Increasing interdependency between electric power systems and natural gas systems creates additional dimensions of flexibility of system operation; but it may also escalate risk levels if the two systems are managed without proper coordination.

Quick Convex Hull-Based Rendezvous Planning for Delay-Harsh Mobile Data Gathering in Disjoint Sensor Networks

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2019
Sink mobility is a significant technique to improve the performance of wireless sensor networks (WSNs). Generally a mobile sink visits several rendezvous points (RPs), forming a trip tour for data collection.

Convex Hulls on Cellular Automata

2010
In the cellular automata domain, the discrete convex hull computation rules proposed until now only deal with a connected set of seeds in infinite space, or with distant set of seeds in finite space. We present a cellular automata rule that constructs the discrete convex hull of arbitrary set of seeds in infinite spaces.
