Scaling an SEO agency is incredibly challenging, especially when it comes to the most resource-intensive aspect of the job: acquiring high-quality backlinks.

Google claims to have developed a quantum computer algorithm that is 13,000 times faster than the most powerful supercomputers. This would bring the technology another step closer to real-world ...

The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

Abstract: In this paper, Heawood's counterexample graph is artificially colored by using the algorithm of planar graph four-colorable based on path homotopy search, which verifies the feasibility and ...

Abstract: This paper improves Itai and Rodeh's algorithm for finding a shortest cycle in an undirected unweighted graph. Given an undirected unweighted graph G with n vertices,the algorithm can ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

Graph theory is an integral component of algorithm design that underlies sparse matrices, relational databases, and networks. Improving the performance of graph algorithms has direct implications to ...

ABSTRACT: In 2012, Ponraj et al. defined a concept of k-product cordial labeling as follows: Let f be a map from V( G ) to { 0,1,⋯,k−1 } where k is an integer, 1≤k≤| V( G ) | . For each edge uv assign ...

If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a slippery concept. Perhaps one day there’s an accident or road closure ...

I know that for chordal graphs, Sage has a function to recognize a perfect elimination ordering. This problem is somewhat similar, identifying chordal bipartite graphs. The following theorem is ...

This summer, digital music culture was dominated by club classics and Sapphic bops. But what if you’re looking for something a little off the beaten path? Finding songs and musicians you love requires ...
