perplexus.info :: General : Reproduce this drawing

Reproduce this drawing (Posted on 2005-11-25)

What is the minimum number of strokes to reproduce the drawing below without lifting up the pencil from the paper (no tricks at all), and without passing over a line segment (or part of it) already drawn? You may begin and end wherever you like, and line segments may cross each other, but only as intersections.

Note: a new stroke occurs when a line type ceased because you have to stop and change direction.

Solution: (Hide)

Though the note to define what is a "stroke", at least in this puzzle, most of the users were more concern in question what is a "stroke" than to achieve an answer. Those who answered 14 strokes (not counting the first traced line) or 15 strokes (counting the first traced line as a stroke), could consider to have solved the puzzle.

One solution with "14" strokes accordingly to the note (or "15", if you count the first line) is:

Start at L, and trace these lines:

L----C--(1)--B--(2)--N--(3)--J--(4)--G--(5)--L--(6)--K--(7 - whole circle - back to K)--(8)---A--(9)--O--(10)--M--(11)--D--(12)--F--(13)--M--(14)--L.

There are many others symetric ways.
