对于大型仿真，NetLogo是否太慢?如何加快NetLogo模型的速度? [英] Is NetLogo too slow for big simulations? How can I speed up a NetLogo model?

问题描述

NetLogo是大型模型(> 10,000个补丁，乌龟)的好平台吗?

Is NetLogo a good platform for big models (>10,000s of patches, turtles)?

如何加快运行速度非常慢的模型?

How can I speed up a model that runs very slowly?

推荐答案

我们刚刚发表了一篇有关NetLogo执行速度的文章.可以在以下网站上找到它: http://jasss.soc.surrey.ac. uk/20/1/3.html

We just published an article on execution speed of NetLogo; it is available at: http://jasss.soc.surrey.ac.uk/20/1/3.html

本文的主要观点是:(a)NetLogo在执行大型科学模型时不一定慢，并且实际上在速度上优于某些替代方法； (b)NetLogo模型起初执行速度通常很慢，但是通过使用一些基本技术，几乎总是可以大大加快其运行速度.我们提供了逐步的策略来衡量和提高执行速度.我们还确定了用于NetLogo模型的有效分析(灵敏度分析，参数拟合等)的工具.

The article's main points are (a) NetLogo is not necessarily slow for executing large scientific models, and in fact has speed advantages over some alternatives; and (b) NetLogo models do often execute very slowly at first but can almost always be sped up dramatically by using a few basic techniques. We provide a step-by-step strategy for measuring and improving execution speed. We also identify tools for efficient analysis (sensitivity analysis, parameter-fitting, etc.) of NetLogo models.
