George Forsythe’s last paper

May 25, 2018

When looking for a link in a recent post, I came across Richard Brent’ arXival of historical comments on George Forsythe’s last paper (in 1972). Which is about the Forsythe-von Neumann approach to simulating exponential variates, covered in Luc Devroye’s Non-Uniform Random Variate Generation in a special section, Section 2 of Chapter 4,  is about […]

independent random sampling methods [book review]

May 16, 2018

Last week, I had the pleasant surprise to receive a copy of this book in the mail. Book that I was not aware had been written or published (meaning that I was not involved in its review!). The three authors, Luca Martino, David Luengo, and Joaquín Míguez, of Independent Random Sampling Methods are from Madrid […]

Next June, at the same time as the ISBA meeting in Edinburgh, which is slowly taking shape, there will be an Analysis of Algorithms (AofA) meeting in Uppsala (Sweden) with Luc Devroye as the plenary Flajolet Award speaker. The full name of the conference is the 29th International Conference on Probabilistic, Combinatorial and Asymptotic Methods […]

je reviendrai à Montréal [MCM 2017]

November 3, 2016

Next summer of 2017, the biennial International Conference on Monte Carlo Methods and Applications (MCM) will take place in Montréal, Québec, Canada, on July 3-7. This is a mathematically-oriented meeting that works in alternance with MCqMC and that is “devoted to the study of stochastic simulation and Monte Carlo methods in general, from the theoretical […]

ratio-of-uniforms [#2]

October 31, 2016

Following my earlier post on Kinderman’s and Monahan’s (1977) ratio-of-uniform method, I must confess I remain quite puzzled by the approach. Or rather by its consequences. When looking at the set A of (u,v)’s in R⁺×X such that 0≤u²≤ƒ(v/u), as discussed in the previous post, it can be represented by its parameterised boundary u(x)=√ƒ(x),v(x)=x√ƒ(x)    x […]
