Is almost useless because nobody is going to raise yours salary for that! Or maybe someone will?!? Let’s say we ignore all the benefits of all the optimizations our benevolent compiler is going to made on our code, and have a look at what happen when we execute some hundreds of thousands of times two very… Continue reading Almost useless knowledge
Sometime you really want a book, but you cannot find the damn book anywhere! This is the case of Competitive Programming 3, which friends of mine referred to me many times, so I decide to give him a try. First place where normally I look for books is A., but no luck there. Then I… Continue reading Lulu
An entire post covering both the theoretical part and the implementation is going to take too long, for this reason I’m splitting the material in two parts: A post with some theory introduction, and one post which will be focused on implementation details. The algorithm I would like to show you is the Ukkonen method for… Continue reading Suffix trees.
Since I’m having some hard time in understanding the implementation of all the on-line algorithms for the construction of suffix-tree, I decided to move on buying some additional books which supposedly are going to cover more clearly those topics. Technical books are outrageously expensive, and when you think you’re able to save some money by… Continue reading Sorry, this item can’t be shipped to your selected address.
The last two weeks were pretty unusual, Magda moved to my apartment in Gdansk because finally she found a job here. She had her first day at work last week, at the beginning going to work was problematic since she knew nobody at the office which could pick her up and the only way to reach… Continue reading Coming back to normality.
I’m back in Poland, with a bag full of wine, cheese and a good quantity of prosciutto! Watching out of my office window the first thought running in my mind is “How the hell can I live in a place so cold?!?”, from +20 to -2, from running under the sun in Santa Severa to walking to my… Continue reading Short summary of our holiday.
I wasn’t programming very much in the recent period, I’m still deep involved in my combinatorics book and in a couple of papers on the Ramsey Theory, additionality in the evening before I go to bed –or when I’m in the bed– I spent few time on my new book on text algorithms. Sometime I… Continue reading Ain’t I’m tired, I’m exhausted!
This was a very long week! Most of my free time I was at the gym or on my combinatorics book learning fancy details about the pigeonhole principle, which is very simple but with large implications in problem solving. The pigeonhole principle basically say that if you want to put three pigeon in two holes,… Continue reading Summary for the week.
Back in the days, when computer were used by real computer users and nobody knew what a mouse is, the preferred input device was also the only input device: The Keyboard! When the hipster revolution began back in the seventies/eighties, the proliferation of the mouse users increased dramatically, the keyboard was still the preferred computer input… Continue reading The real keyboard.
