I've finally got around to uploading a close-to-final draft of my PhD thesis (defended in early 2015). As the title suggests, the work is focused on describing several enhancements that can help multi-objective evolutionary algorithms (MOEAs) solve computationally-intensive optimization problems in a decent time frame. Large parts of the main novel scientific contributions of this thesis have

This journal article describes findings in one of the three main research foci I've investigated during my PhD research project. It is an improved and extended version of the conference manuscript prepared for ICAISC 2013. Here is the abstract of the article: In the last two decades, multi-objective evolutionary algorithms (MOEAs) have become ever more used in scientific&nbsp

This journal article also stems from my PhD research project - enhancing currently available Evolutionary Computation methods employed for solving computationally-intensive multi-objective optimization problems. The presented algorithm - DECMO2 - is an improved version of a method presented in one of our earlier papers. Here is the abstract of the

This paper was prepared for the EUROCAST 2013 conference and contains a proof-of-concept for DECMO - a simple coevolutionary multi-objective optimization algorithm that, on several problems is successfully able to adopt the search behavior of the most successful strategy it incorporates. This line of research was continued and fully fleshed out in DECMO2 - a subsequent algorithm I

A big part of my current PhD work at the JKU-Department of Knowledge-Based Mathematical Systems is related to the dissemination of our current research (i.e., writing scientific articles). That's why most of my recent / forthcoming posts are / will be about "papers". The work presented in this post is a revised and extended (journal) version of one of the earlier papers written in collaboration

This paper was prepared for the EUROCAST 2011 conference and it basically contains a short summary of the work I have carried out for my Master Thesis Project. Here is the abstract of the article: This research is focused on reducing the average size of the solutions generated by an enhanced GP process without affecting the high predictive accuracy this method exhibits when being applied on a

Evolutionary algorithms (EA) have become very popular for solving complex optimization / data based modeling problems as, generally, they are fairly robust, easy to use and able to produce high quality results. A common problem in real-word applications is the fact that the evaluation/fitness function employed by this type of algorithms is quite expensive (time-wise or even financially) to

In these most auspicious times for social networking, business cloud migration and setting trends on twitter about Justin Bieber, I'll try to draw a bit more attention towards two open-source, free, industry proven, high quality pieces of software that can help you add a little more privacy and security to your personal information (if for whatever conspiracy theory driven reason you would feel

I can work with relative ease with Excel and OpenOffice Spreadsheet but the iWork Numbers application was totally new for me. I was working on a report in Numbers and I didn't know how to calculate the difference in minutes between two date fields and, I must say, that I didn't find the information I needed fast enough on the web. To keep the long story short, after 2-3 minutes of trial and

As promised in my previous post regarding code bloating in GP, here is my Master's Thesis. Hopefully the version I've uploaded doesn't contain too many mistakes (scientific or language wise), but if you find any, please do let me know. You can download a close-to-final draft of the paper by clicking here or from my Downloads box (Zavoianu Ciprian - Master's Thesis.pdf). The same version of

In this post I'll try to present some information regarding the main subject of my Master's Thesis which is entitled "Towards Solution Parsimony in an Enhanced Genetic Programming Process" (sounds a bit bombastic, I know :P). Work on this paper has been carried out at the Heuristic and Evolutionary Algorithms Laboratory (HEAL) in the Hagenberg Softwarepark, Austria. My research was coordinated

During work on my Master Thesis here in Austria I came across two very useful websites.  The first one provides a very fast online plotting tool for 2D and 3D functions that allows the user to specify basic viewing options. The resulting images can be saved in various formats. Another very nice feature is the permalink option which basically allows users to share their plots with others.

I spent most of my time at the e-Austria Research Institute in Timişoara, Romania working with a team that was involved in the European FP7 Research Project DEHEMS. My main task was to design and implement a robust sensor simulation system. I worked on this task with my colleague, Ciprian Craciun, who's insight into the matter at hand and experience helped tremendously. . The resulting

A few months ago I had to solve a pretty interesting, though not very difficult, assignment for my Machine Learning class.  I really think that this is the very first lecture in any Machine Learning Class around the world. . So, given a data set containing 4 distinct features and 2 possible outcomes (or classes, noted for simplicity with -1 and +1) the task was to determine if any of the 4
