Adam Chehouri's Blog

I am very excited to share my first publication in computational intelligence. I began working on the constraint-handling technique in the month of February 2015, as I was trying to find a way to introduce the wind turbine design constraints into my optimization algorithm. Inspired the motif of preserving the core notions of evolution in genetic algorithm by refusing to add a penalty function to the fitness function, I proposed my constraint-handling technique named VCH ( Violation Constraint-Handling ). 


Abstract 
Over the years, several meta-heuristic algorithms were proposed and are now emerging as common methods for constrained optimization problems. Among them, genetic algorithms (GA's) shine as popular evolutionary algorithms (EA's) in engineering optimization. Most engineering design problems are difficult to resolve with conventional optimization algorithms because they are highly nonlinear and contain constraints. In order to handle these constraints, the most common technique is to apply penalty functions. The major drawback is that they require tuning of parameters, which can be very challenging. In this paper, we present a constraint-handling technique for GA's solely using the violation factor, called VCH (Violation Constraint-Handling) method. Several benchmark problems from the literature are examined. The VCH technique was able to provide a consistent performance and match results from other GA-based techniques.

AbstractWithin the last 20 years, wind turbines have reached matured and the growing worldwide wind energy market will allow further improvements. In the recent decades, the numbers of research papers that have applied optimization techniques in the attempt to obtain an optimal design have increased. The main target of manufacturers has been to minimize the cost of energy of wind turbines in order to compete with fossil‐fuel sources. Therefore, it has been argued that it is more stimulating to evaluate

A year ago, I received an invitation from my university to participate in the known competition of ''Présenter Ma Thèse en 180 Secondes''. Like the many emails I receive, I did not give it any value, and to be honest I was busy preparing for my doctoral exams. Also, I had just terminated my first year and all I had really conducted was a very long bibliographic review. I was just beginning to understand my thesis and a year later, I can honestly say that many of the initial objectives have been modified and my research has a new set of targets. 

Long story short, this year I received the same invitation, and for some reason I starred the email and took note to maybe give it more consideration this time. I replied to the organizer at my university and asked him to send me more information regarding the competition.
I won and will be representing the Université du Québec à Chicoutimi at the national finals (more details).


The competition is inspired from the English version Three Minute Thesis that was held for the first time at the University of Queensland, Australia in 2008. This year, the national championship will be featured at the 84eme Congrès de l'Acfas on May 11 2016 at the Université du Québec à Montréal. The winner will then go on to represent Canada at the international finals that is scheduled to take place in Rabat, Morocco on September 29 2016. 
Next step... Montreal :)

I am going to start something new today. Honestly I do not know how long it is going to last but, ideally I would like it to continue. It began this morning when I took a look at a cover photo I had just uploaded yesterday to facebook prior to my amazing long weekend in Ottawa, ON, Canada.
Like many of us, we all have 'it', that quote, that poem, that picture that we revert to every often to reflect on our present events, remember loved ones or even send out an sos. Whatever the case may be, these words define who we are so why not share them. Let them describe us and let us take a step back from using the 'I'.
Without any preferences, here are the quotes that I've carried softly close to my heart in the past years. 


Send your personal cover by email to a friend or loved one, you can even upload it on social media and tag your friends. In the spirit of love, let us reveal our true colours.

I know there are many image editors available on the web, but I used Pixrl Express. Browse your image, add your words and share.

One Love.

I am really excited in sharing with you this Webinar by Elsevier Publishing Campus on how a researcher should deal with the reviewer's comments. I really encourage young researchers to sign up to Elsevier Publishing Campus for free lectures and very interactive training. Whether it be your interested in writing a journal article, wondering how the peer review process is conducted or even understanding publishing ethics, whatever it may be, EPC has many resources to help researchers achieve some of their goals. 
Often enough, authors are asked to revise their paper with minor or major revisions and in many other likely cases the paper is rejected. Regardless of the type of response, the authors receive a series of comments that have been forwarded from the reviewers to the editor .I've just finished listening to this webinar and I found it to be very well-structured, informative and includes a compilation of key points to remember the next time we deal with response letters. In fact, I have just received a decision letter this morning and unfortunately for the second time in a row with the same journal, my paper has been rejected. 
The best advice is to stay positive and remember it is not a sprint, it is a marathon !
