Constrained Submodular Maximization: Beyond 1/e
- Computer Science, Mathematics2016 IEEE 57th Annual Symposium on Foundations of Computer Science (FOCS)
- 2016
This work finds an approximate fractional solution for maximizing the multilinear extension of the function over a down-closed polytope and it is the first improvement over the 1/e approximation achieved by the unified Continuous Greedy algorithm.

Chance-Constrained Submodular Knapsack Problem
- Mathematics, Computer ScienceCOCOON
- 2019
This study considers the chance-constrained submodular knapsack problem, where a set of items whose sizes are random variables that follow probability distributions are required to find a subset of items that maximizes the objective function subject to that the probability of total item size exceeding theknapsack capacity is at most a given threshold.
A Faster Tight Approximation for Submodular Maximization Subject to a Knapsack Constraint
- Computer Science, MathematicsArXiv
- 2021
It is proved it suffices to enumerate only over all subsets of size at most two and still retain a tight (1 − e)-approximation, which improves the running time from O(n) to O( n) queries.

An analysis of approximations for maximizing submodular set functions—I
- MathematicsMath. Program.
- 1978
It is shown that a “greedy” heuristic always produces a solution whose value is at least 1 −[(K − 1/K]K times the optimal value, which can be achieved for eachK and has a limiting value of (e − 1)/e, where e is the base of the natural logarithm.
Maximising Real-Valued Submodular Functions: Primal and Dual Heuristics for Location Problems
- BusinessMath. Oper. Res.
- 1982
A slightly more specialised model is examined that generalises the location problems of interest, but now also includes the continuous aspects of the problems missing from the earlier model, namely the problem: max{wy: Σj=1najyj ≤ b, 0 ≤ yj < 1} of maximising a real-valued nondecreasing submodular function subject to a knapsack constraint.
Constrained Maximum-Entropy Sampling
- Computer ScienceOper. Res.
- 1998
Using techniques of linear algebra, combinatorial optimization, and convex optimization, upper and lower bounds on the optimal value for the Gaussian case are developed and integrated into a branch-and-bound algorithm for the exact solution of these design problems.
An Exact Algorithm for Maximum Entropy Sampling
- Computer ScienceOper. Res.
- 1995
An upper bound for the entropy is established, based on the eigenvalue interlacing property, and incorporated in a branch-and-bound algorithm for the exact solution of the experimental design problem of selecting a most informative subset, having prespecified size, from a set of correlated random variables.
