AI tools are increasingly replacing human judgments in some settings. For instance, resume-screening algorithms are often ...

As data science continues to evolve, the k-means clustering algorithm remains a valuable tool to uncover insights and patterns within complex datasets. Understanding the elbow method and the ...

The library sorting problem is used across computer science for organizing far more than just books. A new solution is less than a page-width away from the theoretical ideal. Computer scientists often ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

People have performed many mathematical proofs to show that a quantum computer will vastly outperform traditional computers on a number of algorithms. But the quantum ...

If you are looking to pursue a career in computer science, you may have wondered what, if any, discussion exists around ethics in this field. The good news is that computer science ethics is an ...

Algorithms have taken on an almost mythical significance in the modern world. They determine what you see on social media and when browsing online, help form people’s belief systems, and impact the ...

The original version of this story appeared in Quanta Magazine. Imagine a town with two widget merchants. Customers prefer cheaper widgets, so the merchants must compete to set the lowest price.

Formulate sequential decision-making problems as deterministic decision processes, Markov chains, and finite Markov decision processes. Explain and apply core reinforcement learning concepts, ...

A subplan is an optional enhancement to the Professional MS in Computer Science (MSCPS) degree program allowing students to demonstrate a high level of expertise in a sub-field of Computer Science.
