We smooth the greedy algorithm via randomization, and prove that it almost recovers original approximation guarantees in expectation for the cases of cardinality and 魏-extendible system constraints. We then present how to efficiently compute gradient estimators of any expected output-dependent quantities....
This is one of the reasons why the algorithm converges prematurely. Due to the widespread use of greedy selection methods, the survivor selection method defined in step 3 is one of the least studied topics in the design of MHS algorithms. Based on this, Hamdi Tolga Kahraman et al. improve ...
We give aparameterized algorithm GREEDY α that belongs to the class of "myopic" algorithms, which are deterministic algorithms that process the given intervals in order of non-decreasing right endpoint and can either reject or select each interval (rejections are irrevocable). We show that there ...
consequently prolonging the network lifespan as the number of message hops from the sensor node to another to reach the base node will be decreased as a result of using Prim’s greedy algorithm [133] in finding the minimum spanning tree (MST) [134] via establishing the shortest communication...
We present an algorithm, dubbed Multi-Branch Matching Pursuit (MBMP), to solve the sparse recovery problem over redundant dictionaries. MBMP combines three different paradigms: being a greedy method, it performs iterative signal support estimation; as a rank-aware method, it is able to exploit ...
My generator implements what's known as a greedy algorithm. This means that the algorithm makes every valid move it finds, even if not making a valid move might ultimately create a better overall result. As with many greedy algorithms, while it doesn't produce an optimal result, it produces...
In order to enhance its performance, this paper proposes an improved flower pollination algorithm, combined with three strategies, i.e., a new double-direction learning strategy to advance the local searching ability, a new greedy strategy to strengthen the diversity of population and a new ...
Also, sometimes there are questionable greedy algorithms whose correctness becomes obvious once you think about the DFS tree. The DFS tree Consider an undirected connected graph GG. Let's run a depth-first traversal of the graph. It can be implemented by a recursive function, perhaps something...
