Jacobi equipped with constraints… (Michel Caillaud, Nicolas Dupont, François Labelle)

Jacobi: constraints

An article by Michel Caillaud, Nicolas Dupont, François Labelle explains and illustrates a new tool to solve some complicated fairy PGs offered by the solving program Jacobi – the possibility to add some constraints in the input.
(with gratitude to the authors for offering this article to JF)

…Jacobi constraints let the user specify some or all of a piece’s moves. One design goal was to be able to represent the “strategy” notation displayed by Natch and Euclide when solving a proof game, so the notation is somewhat similar. This common notation includes the “-” and “x” symbols, and a minimum number n of moves played by a piece is marked “(n)”…

The memories of 61st WCCC in Ohrid

Getting back into my daily work after a week on a beautiful Ohrid lake… 

These are the words I’ve heard from the congress participants: “one of the best congresses”, “absolutely wonderful place”, “much over my expectations”, “who could have expected it?..”  etc… And I shared such emotions very much, initially having no special expectations, more like doubts about going to the little town of the unknown far away country.. but! what a beautiful place it was! Thinking later how the nice warm place, friendly people around, old town on the hill covered with the flowers, ancient churches, blue lake surrounded by the mountains, tasty food, live music… it all easily covers all little imperfections in organization 🙂

Yes, I’d say it was very fairy congress, but not only because of the paradise-like place..  Oh, no, the most amazing were the organizers! Absolutely invisible men! Reminded me René J. Millour’s 1st Prize winner, No.838, although Rene had 11 Invisibles, but we had only 2, still much more complicated to find! 

Well, the serious or practical part of the event is already covered more or less in the recent posts at wfcc.ch. And I’ll put some more photos to the 42nd WCSC page soon. But here would gladly share the album I have, free to download if anybody is willing to.
