Kerm, that's definitely recursive division, not DFS. Mine uses a strange algorithm though it can be thought of as a mathematical model of recursive division. I just finished my math final so I'm working on a program the uses Eller's algorithm and another that uses Kruskal's algorithm.
It's definitely depth-first. I should know, I've spent a semester on Honors Analysis of Algorithms, one of my PhD qualifier exams, and an algorithm that explores a tree depth-first rather than breadth-first is a depth-first search algorithm. Just because it happens to be a pre-order DFS doesn't change that it's a DFS. I could just as easily draw the edges inorder or postorder. In this case, the DFS tree has cells on its vertices, and smaller cells are deepest into the tree.

@Weregoose, nice job.
Algorithms definition vs. Mazing definition. Meh. I'm working on one now that creates a maze one row at a time and doesn't store the while maze in memory. Though I'm pretty sure it won't be faster than the other I posted.

Ah, good luck on that. I doubt that Maze generators re-invented the definition of a depth-first search, though.
On most Mazing websites DFS is synonymous with a recursive backtracker.
Weighing in at 220 bytes, using very little memory (it doesn't even store any of the maze in memory, the algorithm only has knowledge of the current row!), though it takes about 3 minutes per render

Code:
```ZStandard 84 -> Xmax 52 -> Ymax For(A,-10,84,2 VerticalA HorizontalA End seq(B,B,1,47 -> L1 A -> C For(A,1,61,2 For(B,1,46 If (randInt(0,1) or A=61) and L1(B)=/=L1(B+1 Then (L1)(L1=/=L1(B+1 -> L1 L1(B)not(L1)+L1 -> L1 Pxl-Off(A,2B End End For(B,1,47 If A=/=61 and (randInt(0,1) or 1=sum(L1=L1(B Then Pxl-Off(A+1,2B-1 Else C -> L1(B C+1 -> C End End End```
Not bad, not bad at all. I see a few tiny optimizations, but nothing major. Also, please use [code] tags around your code.
