Submodular optimization problems and greedy strategies: A survey [PDF]
Discrete Event Dynamic Systems, 2020 The greedy strategy is an approximation algorithm to solve optimization problems arising in decision making with multiple actions. How good is the greedy strategy compared to the optimal solution? In this survey, we mainly consider two classes of optimization problems where the objective function is submodular. The first is set submodular optimization,

Optimization of Submodularity and BBO-Based Routing Protocol for Wireless Sensor Deployment
Sensors, 2020 Wireless sensors are limited by node costs, communication efficiency, and energy consumption when wireless sensors are deployed on a large scale. The use of submodular optimization can reduce the deployment cost.

Mobility-Aware Traffic Offloading via Cooperative Coded Edge Caching
IEEE Access, 2020 With caching popular contents at the small-cell base stations (SBSs), cooperative edge caching has emerged as an effective approach to offload explosively increasing network traffic from a massive number of users in mobile edge networks (MENs).

Multivariate Submodular Optimization
, 2016 Submodular functions have found a wealth of new applications in data science and machine learning models in recent years. This has been coupled with many algorithmic advances in the area of submodular optimization: (SO) $\min/\max~f(S): S \in \mathcal{F}$, where $\mathcal{F}$ is a given family of feasible sets over a ground set $V$ and $f:2^V ...

CrossPatch-Based Rolling Label Expansion for Dense Stereo Matching
IEEE Access, 2020 We present a novel algorithm called crosspatch-based rolling label expansion for accurate stereo matching. This optimization-based approach can effectively estimate the 3D label of each pixel from huge and infinite label space and then generate a ...

Online dynamic submodular optimization
AutomaticaWe propose new algorithms with provable performance for online binary optimization subject to general constraints and in dynamic settings. We consider the subset of problems in which the objective function is submodular. We propose the online submodular greedy algorithm (OSGA) which solves to optimality an approximation of the previous round loss ...
