At first, Eppstein liked minimum spanning trees. (4)

I spent a splendid week at Schloss Dagstuhl for Dagstuhl Seminar 14451: Optimality and tight results in parameterized complexity. As usual, this was intellectually extremely stimulating and very exhausting.

My head is full of tempting research ideas that I immediately need to pursue. Instead, I finalised a small cryptic crossword about parameterized complexity. If you are in the tiny demographic targeted by this puzzle, enjoy!
