How do you count rooted planar n n-ary trees with some number of leaves? For n = 2 n = 2 this puzzle leads to the Catalan numbers. These are so fascinating that the combinatorist Richard Stanley wrote ...

Abstract: For increasingly complex real-world optimization problems, a large number of researches have shown that differential evolution (DE) is an effective problem-solving algorithm. Despite its ...

Minecraft Snapshot 25W09A introduces new fallen trees at various biomes. Now, the firefly bushes spawn in Mangrove biomes rather than badlands. Finally, the leaf litter blocks have become replaceable ...

Now that we’re getting into more complex data structures, having more complex operations, it’s helpful to have a tool for visualization. Here’s a tool developed by David Galles, formerly of University ...

A binary heap is a binary tree with two constraints: the heap order property and the structure property. The heap order property ensures that child nodes are always ordered with respect to their ...

ABSTRACT: In combinatorics, permutations are important objects with many operations. In this paper, we define a coupling product on permutations and prove that the space spanned by permutations is a ...

Abstract: Various methods have been introduced and developed to analyze fault tree diagrams. One of the interesting methods is fault tree conversion to Binary Decision Diagram (BDD). However, the ...
