(see Logic Masters 2013)
Divide the grid into two areas, and solve one of these as a Masyu, the other as a Zwischenknick.
Masyu: Loop that travels from cell centre to cell centre, visiting each clue circle, and turning immediately before and/or after each white clue.
Zwischenknick: Loop that travels from cell centre to cell centre, visiting each cell, turning in each white clue, and turning exactly once between two clues on the loop.
Solution code: The lengths of the horizontal segments for each of the marked rows, 0 for rows without horizontal segments.

Bildlinks korrigiert. Seltsam, aus '0002NN' ist irgendwann '00002NN' geworden.

Thanks! In the English it says "visiting each clue"...and uses the same word "clue" for the circles...

@RALehrer: Rules are the same in example and here - at least in the German version it says "visiting each cell" (alle Felder besucht).

to clarify: does the zwischenknick have to cover all squares as in the LMI example, or not as per the written rules here?
