Jónas Tryggvi - CV

Information

My name is Jónas Tryggvi Jóhannsson (jonas@jonastryggvi.com) and I'm a 31 years dude living in downtown Reykjavík with my wife.

Education

1. Reykjavík University MSc. in Computer Science, January 2007
   • Teachers assistant in "Distributed Systems"
   • Masters Project: "Automatic Weight Tuning in Heuristic Evaluation Functions"
     • Supervisor: Dr. Yngvi Björnsson
     • My project involved exploring the differences between Reinforcement Learning algorithms, focusing on TD(λ) and TD-Leaf(λ), which are commonly used for tuning weight coefficients for heuristic evaluation functions used in game playing programs. I implemented these algorithms in C++ as an extension to an already established chess playing program called Fruit, and later generalized those ideas as a framework for use with any game playing program.
   • Spent two semesters abroad;
     • Technical University of Denmark (DTU), fall 2005
     • University of Alberta, Canada, spring 2005
2. Reykjavík University BSc. in Computer Science, May 2004
   • Bachelors Project: "Using overlays as a control plane for mutlticast"
   • Supervisor: Dr. Gísli Hjálmtýsson
   • We designed an location aware overlay network (p2p network), to use as a self configuring control plane for internet multicasting. The overlay was built to be a part of the Self-configuring Lightweight Internet Multicast, or SLIM, solution that was being developed at the University of Reykjavik. The purpose of the overlay was to assign new nodes to their nearest super-peer, in order to created efficient multicast streams and distributing it to subscribers.
   • Spent one semester at Technical University of Vienna, Austria, Spring 2003

I started programming for the Web in different scripting languages, but later learned to enjoy using Java for projects in my university and quickly became a Java fan with great interest in the JVM. I have also been programming in C++ when the projects involved memory or cpu intensive calculations, and I did my masters project in C++. For the last year, I've been programming in Java, Python and Ruby - which I consider to be a beautiful and productive programming language.
