Dear all, we hope all is well with final exams and project 5. We have been made aware of the fact that many of you this year have exams close to our deadline for project 5, December 15.

We decided thus to move the final deadline to December 18 at the devilrish time 2359 (1159pm), hoping this can be of help. That is the final deadline. 

Dear All, this is our last week and our last lecture is Thursday (no lecture on Friday, only lab). 

We will end our discussion of Partial differential equations (chapter 10 of lecture notes) with hints and practicalities related to the various variants of project 5, before we summarize what we have done this semester. We will also present some future research directions in computational science, with potential master of science thesis topics and/or courses of interest for many of you. 

Else, both Thursday and Friday we will have our regular lab sessions. These are also the last lab sessions this semester. 

It has been a great pleasure to get to know you all and we wish you all the very best,

Aram, Daniel, Halvard, Jonas, Morten and Sebastian

Small addendum to weekly FYS3150/4150 plans

Hi all, I forgot to say that for those of you interested in object orientation in C++ (of interest for those of you who plan to do the solar system variant for p5), we will have a small session from 10.15-12 (approx) at the lab tomorrow. Most likely we will move over to room F?465 at the center for computing in science education (same floor as the lab on Fridays).   If you wish to just hear about this as well, please feel free to join.  We meet at the lab and then move eventually on to another room.

Furthermore, for those of you working on other variants of project 5, if it is of interest we can suggroup discussions on Friday and next week as well.

Best wishes to you all,

Morten

Hi all and thx so much for fantastic efforts with project 4. We are getting close to the end of the semester, sadly and 15 weeks have flown away. Our last topic is partial differential equations linked up with two of the final variants of p5. Tomorrow and Friday we will discuss in depth the diffusion equation in one and two dimensions as well as Poisson's and Laplace's equations in 2-dim. Our last lecture on PDEs (wave equation in 1 and 2 dims) is next Thursday, with a summary as well. There is no lecture on Friday the 29th of November, only lab. Our last lab sessions are thus next week, Thursday (28) and Friday (29). Next Friday we will end the semester with pizza at the lab as well!

Best wishes to you all!

The fys3150/4150 gang.

Good morning everybody!

Here's a short update, with plans for this week and the final two ones.

Last week we started with ordinary differential equations and derived the Velocity Verlet algorithm.  We continue this week with the Runge-Kutta family of methods and derive the most famous one, the RK4 method and discuss also adaptive ODE methods. We will thereafter move over to partial differential equations (PDEs) with the diffusion equation first on Friday. We continue with PDEs next week as well, before we wrap up our course during the last week. Project 5 is also out, there are presently 7 variants!  The variant based on the Ising model for modeling of elections is not yet ready. Furthermore, there will be an additional project on PDEs (thanks to Hilmar). These two will be posted over the weekend.

The deadline for project 5 is set to December 15. Unfortunately we cannot extend the deadline beyond that, mainly due to grading deadlines at UiO...

Good morning everybody, just a short message this time about the plans for week 45.

On Thursday we will wrap up our Monte Carlo discussions, pointing at possible other applications and finalize the discussion on the calculation of errors.  The material on error discussions and the central limit theorem can be found in the lecture notes chapter 11.2.  After this we start with our last topic, ordinary and partial differential equations (chapters 8 and 10 of the lecture notes). We start with ordinary differential equations (ODEs) this week (most likely towards the end of the Thursday lecture) and will focus on the standard methods like the family of Runge-Kutta methods and so-called symplectic ODEs, see chapter 8 of the lecture notes. Thereafter, towards the end of next week, we start with partial differential equations and that will keep us busy till the end of the semester. 

At the l...

Dear all,

last week we discussed in detail the technicalities of project 4 and linked the Ising model with the Monte Carlo algorithm and the sampling rule for accepting or rejecting a move. The latter lead us to the Metropolis algorithm.

We will derive it this Thursday (see chapter 12.5 of the lecture notes)  and we will also continue our discussion of project 4 this Thursday and parts of Friday. Most of these technicalities are covered by chapter 13 of the lecture notes. 

Friday we will need to go back to chapter 11 and discuss some statistics which is related to our understanding of errors and how we compute them in a reliable way. This will lead us to the central limit theorem and the calculation of statistical quantities like the covariance (covered by chapter 11.2 of the lecture notes). Hopefully this can lead to a better understanding on how we compute the standard deviation from a Monte Carlo calculation.  

&nb...

Hi all and thx a million for heroic efforts with project 3!!!  We really appreciate what you have done and are very impressed. We look forward to read your projects.

Project 4 is out and we will discuss the mathematics and science behind this project during tomorrow's and Friday's lectures. During these lectures we will also derive the Metropolis algorithm, discuss Markov chains and link this to the statistical physics of project 4. The material of relevance can be found in chapters 12 and 13 of the lecture notes, as well as the slides on Markov chains and brownian motion at http://compphysics.github.io/ComputationalPhysics/doc/pub/rw/html/rw.html

and the slides on statistical physics and project 4 at ...

Hi all and welcome back to FYS3150/4150. We obviously hope that the midterm week fared well with you all. 

Here's a brief update on our plans for this week and the next two ones wrt Monte Carlo methods. 

On Thursday we will wrap up our discussions about project 3, in particular repeat some basic elements if 3a and 3b as well as discussing multidimensional integrals with Monte Carlo methods. The latter material, with a similar example relevant for 3c and 3d is covered by the lecture slides (see the last slides) at for example http://compphysics.github.io/ComputationalPhysics/doc/pub/mcint/html/mcint.html

Thereafter we will also discuss on Thursday  how to compute random numbers with the random class in C...

Dear all, since many of you are busy with various midterm exams this week (best wishes to you from us) there are no lectures this week, neither on Thursday nor on Friday. 

However, we will keep the lab open and this week there is only project work (no dedicated lectures on special topics at the lab).

Concerning project 3, we recommend looking again at the slides on 

1) Gaussian quadrature at for example http://compphysics.github.io/ComputationalPhysics/doc/pub/integrate/html/integrate-reveal.html and chapter 5 of the lectures

2) Monte Carlo integration, in particular the last part o...
