Algorithmic Engagements is an annual festival for IT specialists in Poland. The noble rivalry over algorithmic ideas and programming skills can be entered by professional programmers, computer engineering students, high school students (or even senior pupils) and virtually everyone who treats computing and algorithmic science as a hobby. The finalists of the competition constitute the elite of young Polish IT specialists what finds its confirmation in their professional and scientific accomplishments. I do hope, that among the former and current Algorithmic Engagements contestants, there will be those, whose professional achievements will cause the word "Poland" appear on the world's lips not only because of our national tragedies. That is what I wish for all and myself in these, difficult for Poland, days.
