In computer science, the "O" in Big O notation is used to describe the upper bound of an algorithm's running time. For example, if an algorithm has a running time of O(n), it means that the algorithm's running time grows most linearly with the size of the input data. This means ...
Being familiar with data structures can also help you when choosing algorithms. Knowing you have a structure that will run your code efficiently is the first step, and then you choose an algorithm in a similar way. Click here to learn more about A Common-Sense Guide to Data ...
You can crack any Interview if you are preparing yourself in a well organised manner. There are lots of Data Structure and Algorithm problems on internet and it is quite impossible for a person to practice all of them. So it is really important that you practice a list of few problems whi...
The quadratic sieve algorithm (QS) is a modern integer factorization algorithm and, in practice, the second fastest method known (after the number field sieve, NFS). It is still the fastest for integers under 110 decimal digits or so, and is considerably simpler than the number field sieve. ...
Besides the community, the hierarchical structure of the network has also attracted attention30. Some previous outcomes have used the hierarchical structure to drive the K-shell decomposition algorithm and its improvements31,32,33,34. Although the K-shell algorithm has promising applications in various...
To identify critical nodes within these networks, we employ the PageRank algorithm and categorize them using centrality and participation indices. Furthermore, we explore the factors that contribute to their influence and observe a clear hierarchical multi-centre structure in Chengdu's trip networks, ...
proposed the SFE algorithm [3] which divides the path search process into two subgraphs and searches for the intermediate entity at the same time, thereby improving the efficiency of path search. In addition, it binarizes the probability matrix to reduce the calculation. However, it still cannot...

After watching all the videos of the famous Standford's CS231n course that took place in 2017, i decided to take summary of the whole course to help me to remember and to anyone who would like to know about it. I've skipped some contents in some lectures as it wasn't important to ...
In the April 2019 NGINX was the most commonly used HTTP server (see Netcraft survey). NGINX is a fast, light-weight and powerful web server that can also be used as a: fast HTTP reverse proxy reliable load balancer high performance caching server full-fledged web platform Generally it ...
