MIT 8.591J Systems Biology, Fall 2014
View the complete course: ocw.mit.edu/8-591JF14
Instructor: Jeff Gore
Prof. Jeff Gore discusses modeling stochastic systems. The discussion of the master equation continues. Then he talks about the Gillespie algorithm, an exact way to simulate stochastic systems. He then moves on to the Fokker-Planck equation.

What a wonderful teacher! I arrived here via Google search for the Gillespie algorithm, but now I think I'll watch the whole course. Just a superbly clear, organized, and engaging presentation. Absolutely first rate.

The portion of Gillespie algorithm starts around 42:08.

I think it really starts around 53:, and he starts writing down the actual algorithm around 56:

Im taking the systems bio class at Stanford, this lecture is really useful!!

I LOVE WATCHING THESE LECTURES so much better than my systems biology masters program :-( I will try to do my PhD at MIT though because in the last 4 years I learned to dream big!

+Liss Taylor so to elaborate: the lecturer has humor and they really engage their students also the class is logically structured and the explanations are good :-)

Hello Sir, hope you are well, today i am writing to know about currently hot topics in stochastic financial models for post graduate research? can you please suggest me some topics?

nice class...but cam operator makes me feel sick by keep moving the camera and zooming in and out...why can't just be held at a steady angle?

Why can't more than one reaction happen at the exact same time? Why do we assume just a single reaction happens at a time point ?

@jp.10103 10 ай бұрын

A reaction could occur more than once, you only update one event at a time. As the computed next time point is pulled from an exponential distribution, there is a probability that it equals 0, which would mean you would record two events for the same time point. For that to happen though the sum of the rates would need to be very large, so usually you get some time between events
