 2   riddles / medium / Re: Duck on a lake with unseen predator  May 15th, 2023, 3:10am 
Started by rmsgrey | Last post by rmsgrey
Here's what I've come up with:
 
The fox cannot guarantee to capture the duck. If the duck swims in circles around the center of the lake just inside the 1/4 radius line, then, no matter what the fox does, the duck will have a greater angular velocity, and, over a long enough period, will sweep through every possible angle from the fox. If the duck circles for long enough, then swims radially to shore at a random angle, there's a chance that the fox is more than 3 radians from the duck and so unable to beat it to its landing point.
 
Against this strategy, the fox can attempt to minimise its time in the dead zone, by running with the duck whenever it's in range, and against it whenever it's out of range.
 
The size of the dead zone depends linearly on how close to the r/4 line the duck is circling (zero at 1 - [pi]/4), while the time the fox can stay out of the dead zone is inversely proportional to how close to the r/4 line the duck circles, so the optimum for the duck under this strategy would be to circle at (5-[pi])r/8.
 
On the other hand, if the fox uses the strategy of heading toward the duck's projected landing point whenever it can beat the duck there, and moving to exit the dead zone as soon as possible on the assumption the duck follows its most obvious projected motion (by whatever method you use to project it), the duck can counter that extremely effectively by hanging out somewhere off center long enough for the fox to take up position directly outside the duck, giving the fox a known starting position that the duck can then escape from provided the fox follows the obvious strategy.
 
To counter that sort of bait-and-escape strategy, the fox can ignore the duck whenever it's inside the r/4 line, picking a position around the circumference randomly and waiting for the duck to emerge and then pursuing it.
 
If that is the optimal strategy, then the fox has a flat 3/[pi] chance of catching the duck.
 
Of course, the duck also has the "flip the table" option of staying in the pond forever.

Amazing! I would've never thought of that. (Slow brain.) Still, the intended answer has to do with a tacit detail, and it concerns the pious woman. Any ideas?

Regarding the remaining mystery, I had a s**t bomb in mind. So, after the squirrel defecates, make it and then take the "bomb" to get out of the room. Oh well, everyone has ups and downs.

Shouldn't it be "an" answer? Even so, the answers differ, so I wonder whether or not Your "answer" is satisfactory. I was thinking of something else, something autochtonous to most riddles, and cast in the same mold as Your answer.

 10   riddles / microsoft / What time is the solar noon?  Oct 13th, 2022, 10:54pm 
Started by jollytall | Last post by jollytall
It seems the forum is sort-of dormant. Still I try.
It is not a microsoft question, I came up with it. The logic of the answer is important.
 
At what time is the sun at its highest position (I guess properly it is called solar noon or culmination)?
