More CL libs on Github

Recently I made available some GP code I had in Common Lisp (see previous post). Today I also put on my github account the library I did for Ant Colony Optimzation (cl-aco) and a few others like parsers for MKP and QAP, but also a very basic CFFI bindings for libLBFGS. Like before, these are … Continue reading More CL libs on Github

GP code on Github

Some time ago I got an email asking for the code of one of my old papers. Unfortunately the code was lost. But that reminded me that I still had some other code that could actually be made available. Essentially, some Genetic Programming (GP) libraries that I did around seven years ago (which in turn … Continue reading GP code on Github

ELS2014: Proceedings, Videos and Slides

The organizers of this year’s European Lisp Symposium made available all the videos of the talks with the respective slides, as well as the PDF containing all the accepted papers. This is really great and everyone involved in making this happening should be congratulated! For everyone that didn’t attend (like me) it’s a good opportunity … Continue reading ELS2014: Proceedings, Videos and Slides

A note on shortcircuiting of argument evaluation in #'<

There is an interesting thread in the Clozure Common Lisp development mailing list about argument evaluation in #'<. Until now, CCL was implementing shortcircuiting when evaluating the arguments of #'<. This essentially means that when calling (< 1 3 2 4 5) it would stop before evaluating all the arguments since it wold know it … Continue reading A note on shortcircuiting of argument evaluation in #'<

zsort: portable sorting algorithms in Common Lisp

zsort is a library that I started working on as a simple hobby project. More or less around the same time I decided to check which algorithms the different Common Lisp implementations use. It is now part of Quicklisp so it can be easily used (thanks Zack!). The main goal of zsort is to be … Continue reading zsort: portable sorting algorithms in Common Lisp

Macros Design Patterns

I was reading the thread What are some fun or useful macros? on reddit and it reminded me of another thread that appeared in the Pro mailing list. These kind of threads are always enjoyable because each time you learn something new and see really interesting things. While reading them, it crossed my mind that … Continue reading Macros Design Patterns
