Finally, CytoSPACE assigns each cell to spatial coordinates in a manner that minimizes a correlation-based cost function constrained by the inferred number of cells per spot via a shortest augmenting path optimization algorithm. An efficient integer programming approximation method that yields similar ...

Transcription Factor regulons and gene regulatory networks were inferred using R package SCENIC (v.1.1.2-2)32 and GRNBoost2 algorithm from python library Arboreto (v.0.1.6). This method (GRNBoost2 algorithm) was chosen on the basis of performance, time and memory usage and low sensitivity ...

The proposed location problem is solved optimally using the geometric branch-and-bound algorithm and heuristically using swarm-based optimization algorithms. The implementation relies entirely on open-source Python packages, allowing the work to be verified, replicated, and expanded upon by the broader ...
单源最短路径快速算法(spfa)的python3.x实现0. 写在最前面最近比较忙呢,写的比较少了。抽空写了一下这篇文档,简陋勿喷~(后面准备做个算法包,包括基础的数据结构和算法,感觉任重而道远)1. SPFA的简介[1]SPFA(Shortest Path Faster Algorithm)算法是求单源最短路径的一种算法,它是Bellman-ford的队列优化,它...
Although it is not expected that the same cell's pseudotimes in different paths are exactly the same, the chance that they are drastically different is very low according to our path selection algorithm. We analyze the consistency between the pseudotimes of the same cell in different paths. ...
