![]() Because with the advent of LLMs our language has become a unique bridge between humans, AIs and computation. And now-in 2023-there’s a new significance to this. Our long-term objective has been to build a full-scale computational language that can represent everything computationally, in a way that’s effective for both computers and humans. From the whole idea of symbolic programming, to the concept of notebooks, the universal applicability of symbolic expressions, the notion of computational knowledge, and concepts like instant APIs and so much more, we’ve been energetically continuing to push the frontier over all these years. So much about Mathematica was ahead of its time in 1988, and perhaps even more about Mathematica and the Wolfram Language is ahead of its time today, 35 years later. And it was wonderful to be able to take (on a floppy disk) the notebook I created with Version 1 and have it immediately come to life on a modern computer.īut even as we’ve maintained compatibility over all these years, the scope of our system has grown out of all recognition-with everything in Version 1 now occupying but a small sliver of the whole range of functionality of the modern Wolfram Language: Last Friday I fired up Version 1 on an old Mac SE/30 computer (with 2.5 megabytes of memory), and it was a thrill see functions like Plot and NestList work just as they would today-albeit a lot slower. We’ve worked very hard to make its design as clean and coherent as possible-and to make it a timeless way to elegantly represent computation and everything that can be described through it. And to me it’s incredible how far we’ve come in these 35 years-yet how consistent we’ve been in our mission and goals, and how well we’ve been able to just keep building on the foundations we created all those years ago.Īnd when it comes to what’s now Wolfram Language, there’s a wonderful timelessness to it. Last Friday (June 23) we celebrated 35 years since Version 1.0 of Mathematica (and what’s now Wolfram Language). It’s only been 196 days since we released Version 13.2, but there’s a lot that’s new, not least a whole subsystem around LLMs. Today we’re launching Version 13.3 of Wolfram Language and Mathematica-both available immediately on desktop and cloud. 2.71828^(4.The Leading Edge of 2023 Technology … and Beyond The actual integration is then just a matter of defining the initial condition and folding update over the Wiener process x0 =, w \ WienerProcess] 1 n = n is the variance of the Wiener process. Wn=Sqrt RandomVariate,NT] Īnd then define the update step of the Euler-Maruyama iteration om = 1 ga =. We first sample the Wiener process from a Gaussian distribution dt =. $\xi$ is a Wiener process which is basically just a rescaled version of $\eta$. Which can easily be converted to the original equation. I write the equations of motion for the harmonic oscillator as a system of first order equations Note that this assumes your SDE to be in Ito-form, which in your case coincides with the Stratonovic-form. I chose the Euler-Maruyama method as it is the simplest one and is sufficient for this simple problem. Of course there are different ways of doing that (a nice introduction is given in this paper). ![]() I think it can be quite instructive to see how to integrate a stochastic differential equation (SDE) yourself.
