We describe a new method for visualization of directed graphs. The method combines constraint programming techniques with a high performance force-directed placement (FDP) algorithm. The resulting ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Background Empirical researchers working with observational data have been slow to adopt modern statistical methods for causal inference, which remain poorly recognised among applied quantitative ...

We present an algorithm for drawing directed graphs which is based on rapidly solving a unique one-dimensional optimization problem for each of the axes. The algorithm results in a clear description ...

To create a directed graph in Python for solving problems on LeetCode, you typically represent the graph using data structures such as adjacency lists.

Transformer models have shown great versatility in modalities, such as images, audio, video, and undirected graphs, but transformers for directed graphs still lack attention. To address this gap, a ...
