Possible tag synonyms

Question

I think that the following tags might be synonyms:

• competitive-game and strategy (where strategy is the better choice)

• path-finding and reachability (with reachability as better choice). Also solvability seems to cover the same concept.

• cutting-problem and dissection

• image and visual (with visual as better choice)

• cryptic-crosswordsletter (occurring only once) and cryptic-crosswords

• treasure-hunt and puzzlehunt (with puzzlehunt or puzzle-hunt the better choice)

• network and graph-theory (where graph-theory is the better choice)

Answer 1

Looks like all of these have been dealt with by now, except :

• network and graph-theory (where graph-theory is the better choice)

Indeed, network (11 puzzles and its description even mentions graph theory) should become a synonym for graph-theory (58 puzzles).
