Dwi'n lecio problemau piwis - oherwydd y cyflythreniad ac am ei fod yn cydfynd a naws bryfoclyd wicked issues. Ond gan mai achosion ydi'r rhain nid problema, dwi'n colli'r elfen gynta, felly ella basa trafferthus yn fwy dealladwy. Diolch

Rwy'n hoffi'r cyflythreniad yn 'problemau piwis' ond efallai nad dyna'r ansoddair gorau!

Oes gynnon ni derm am y rhain? Dyma'r diffiniad:-
 

The concept of "wicked problems" was originally proposed by Horst Rittel (a pioneering theorist of design and planning, and late professor at the University of California, Berkeley) and M. Webber [1] in a seminal treatise for social planning. Rittel expounded on the nature of ill-defined design and planning problems which he termed "wicked" (that is, messy, circular, aggressive) to contrast against the relatively "tame" problems of mathematics, chess, or puzzle solving.

 

Diolch ymlaen llaw
