First, we define the constraint graph manually; then, we present a graph learning algorithm that can search for an optimal graph in a greedy scheme. Finally, we compare the manually defined graphs and learned graphs in terms of graph structure and detection accuracy. We evaluate the performance...

So if you can prove your problem is a matroid then you have an awesome algorithm automatically. And if you run the greedy algorithm for fun and it seems like it works all the time, then that may be hinting that your problem is a matroid. This is one of the best situations one could ...
By default, the Hybrid genetic algorithm is used. The next example illustrates a usage without default values. A binary Sbm prior is used, along with a spectral clustering algorithm for graphs. sol <- greed(Books$X,model=Sbm(),alg=Seed(),K=10) #> #>── Fitting a guess SBM model ...
. This algorithm is correct (in the considered context) since we remove vertices from the strong product, and hence we can only decrease or leave unchanged its independence number.For some graphs, which we take as input, e.g., for a path on \(n \geqslant 6\) vertices, we need to ...
An exhaustive search is implemented in the MaximumClique command, which will take an exponential time on some graphs. By contrast, the algorithm implemented in GreedyClique takes polynomial time, but it may return a clique that is not of maximum size. • The algorithm is a so-called GRASP...
Fast Spectral Theory-based Algorithms for unified dense subgraphs detection in large graphs. We propose and formulate the generalized densest subgraph detection problem (GenDS) and fast detection algorithms based on the graph spectral properties and greedy search, i.e., SPECGDS (SpecGreedy) and GEP...

In order to search out a characterization of a type of greedy algorithms for some class of interval greedoids, we provide a type of greedy algorithm (i.e. Algorithm 1) as follows. After that, we will demonstrate under what conditions for a set system, Algorithm 1 has an optimal solution....
