# An "Oldie" with a twist of lemon

Best Answer Prime, 22 February 2013 - 02:08 AM

I have a cold, my head is stuffed, I feel like an Ogre. I am not figuring out the differential equations to deny hungry Ogre his meal. However, here is some food for thought for those Brain Denizens who took the maiden's side. Indeed, she could go slower. Mayhap, someone will try carrying out the required calculations, make an error and give the maiden a wrong advice.

Spoiler for maiden voyage

To make the contest fair, the maiden should have only so much time for rowing. Having exhausted it, she falls asleep. Whereafter, the Ogre should start blowing at the boat pushing it towards the shore...

I think I need a clarification on "best-strategy pursuit".  Does this mean the ogre will move towards/wait at the point in the circle that is closest to the maiden's current position?  Or does it mean it will try to 'follow' the maiden based on her current trajectory?

The ogre will try to be on the shore where the boat lands before the boat gets there. It is a game. Whoever gets to that point first wins. The rower and ogre each act in their own best interest. The rest is part of the puzzle. The rower can row anywhere on the lake and the ogre can run anywhere on the shore. Assume each can turn on a dime [infinite acceleration, maximum speed.]

Best strategy pursuit means to imply that the ogre will not lie down and take a nap.

And the specific question now is Can the rower overcome a ogre speed ratio of greater than (1 + pi)?.

I was developing a winning strategy for the Ogre based on the inertia of the boat. But then Bonanova added an infinite acceleration.

Spoiler for more geometry for maiden

This looks promising. How much advantage might be gained?

Good Job, Cap'n, you've lowered the bar for M, giving her time for a little
touch-up for the reporters sure to be at the shore covering the story
for CNN.

Can you go beyond 5%?
