The task makes sense only, if for a given set of commands the cfg is unique.

If I want to code "if x=0 then goto y else goto z", I have to write:

JMP_ZERO x y
JMP z

JMP_ZERO x y ends the actual block. JMP z can only be at the end a block, too.
So JMP z has to be a new single statement block?

That's clearly a mistake in the figure.

Unless it implies that the chaos operator can let the program move to next instruction or force a jump to an instruction from the list, an even more "chaotic" (and undocumented) behaviour.

I would normally call you "paranoid" but now I wouldn't be surprised given the low quality of the website recently.

Yes, because you can't have any jump statements (JMP_ZERO above) in the middle of a block.

7 solvers on the 11th of the month! In May 2019 (several people want to cross a river, but there are restrictions...) there were 5 solvers on the 10th. Oded gave one more month to solve the challenge. At last there were 24 solvers on the end of the second month.
By the way - Gadi has removed the edge from 60 to 70 in the sample program.

At least, now the text seems unambiguous enough to ponder this problem...

In my opinion, May19 and Oct18 (different area triangles) were much harder than Oct20.
Perhaps now many frequent solvers actually submitted wrong solutions or no solutions at all due to the unclear/contradictory problem explanation.
At least, this is my case.
As soon as the picture was fixed, the number of correct solutions roughly doubled,
I guess it will further increase in few days, and this month will end up with about as many solvers as July20.

For me, the explanation of uau (#10) was the breakthrough for the understanding of the challenge.

I really doubt that it will come anywhere close to July20.
