A couple of problems with YAC 2012
Hello!
Today at YAC there were interesting data analysis tasks.
I will give a couple of them for those who wish to stretch the brain. If you were at a conference (and Habroid was not a little) and up to date with the decision, then it would be reasonable not to throw out everything that you already know.
')
Puzzles cite from memory.
1. A criminal escaped from prison. Having run out on the parking, he got into the car and disappeared on the road in one of the directions. From prison go two endless non-intersecting directions.
Then a cop runs out of prison, stalking a criminal and gets into his car. The cop machine is faster than the escaped brow, but the cop does not know about it. Also, the cop does not know which way the convict left. Can a cop catch the criminal? Prove it.
2. There is space in the form of a square with equal sides . In the center of the square hanging a wolf. Dogs sit in the corners. The wolf can move around the square as he pleases. Dogs are just around the perimeter. The speed of the dog is 1.5 times the speed of the wolf. When a wolf collides with a dog, the wolf wins (the battle takes place instantly). But two dogs will be able to defeat the wolf. Question. Can the wolf escape from the above space alive?
py.sy. The topic was published bored at the station. The laptop will sit down in an hour. If I am gone, I will announce with comments in the morning.
py.py.sy. The laptop is dying. Good reasoning. Tomorrow I will join. And add one more puzzle.
