Hi Petr. Thanks for your posts, and efforts in the field of CP. Regarding the "upsolving", term is cool and already in use by large community (Russian-speaking), and they are also pioneering the field with their nonpareil quality of knowledge and commitment. Specific terms or field-related ones have generally been coined by the masters of the field. For instance, "Id, ego and super-ego", "Oedipus complex", etc were products of Sigmund Freud; "Electra complex" was introduced into the psychoanalytic field by his early student Carl Jung, (trivia) with whom, ultimately, Freud broke off all relations.

Note: No offence was intended on other nations.

Language is formed by usage. The word "upsolving" hasn't been a valid English word and it certainly sounds weird when you first encounter it. However, I'm not aware of any single dictionary word that could be used to describe the process and wouldn't feel awkward. So let's just go ahead and let's call it upsolving. If enough people do so, it becomes a valid word :)

Also, the next generation can then wonder about its meaning the same way the current generation wonders wtf do the words "dynamic programming" actually mean :)

I've already asked on Quora about "upsolving", looks like there is no established word for competitive programming, but there are several similar from other areas.

I've read the title as "A week with Merlini".
