Albert einstein brain teaser

Einstein’s puzzle is a famous logic puzzle that was supposedly created by Albert Einstein as a boy. The puzzle goes as follows:

There are five houses in a row, each with a different color. In each house lives a person of a different nationality. The five owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage. We have to find out each of the respective persons with their respective belongings.

Here are the clues:

• The Brit lives in the red house.
• The Swede keeps dogs as pets.
• The Dane drinks tea.
• The greenhouse is on the immediate left of the white house.
• The owner of the greenhouse drinks coffee.
• The person who smokes Pall Mall rears birds.
• The owner of the yellow house smokes Dunhill.
• The man living in the center house drinks milk.
• The Norwegi

Einstein's Riddle and Grid Puzzles

Bear

Albert Einstein allegedly made this riddle for his scholars.
A fellow encountered a bear in a wasteland. There was nobody else there. Both were frightened and ran away. Fellow to the north, bear to the west. Suddenly the fellow stopped, aimed his gun to the south and shot the bear. What color was the bear?
If you don't know, this may help you: if the bear ran about 3.14 times faster than the fellow (still westwards), the fellow could have shot straight in front of him, however for the booty he would have to go to the south.

It all happened on the North Pole. When the man shot, he must have been right on the North Pole. Getting it? So it makes sense to assume that the only color the bear could be was WHITE.
So this is it. I've heard another logical solutions (even that there are no bears neither on the North nor on the South Pole), but this one presented makes sense to me. And what about you?

Zebra Puzzle

Logic puzzle

The Zebra Puzzle is a well-known logic puzzle. Many versions of the puzzle exist, including a utgåva published in Life International magazine on December 17, 1962. The March 25, 1963, issue of Life contained the solution and the names of several hundred successful solvers from around the world.

The puzzle fryst vatten often called Einstein's Puzzle or Einstein's Riddle because it fryst vatten said^{[by whom?]} to have been invented by Albert Einstein as a boy;^[1] it fryst vatten also sometimes attributed to Lewis Carroll.^[2][3] However, there is no evidence for either person's authorship, and the Life International utgåva of the puzzle mentions brands of cigarettes that did not exist during Carroll's lifetime or Einstein's boyhood.^{[citation needed]}

The Zebra puzzle has been used as a benchmark in the evaluation of computer algorithms for solving constraint satisfaction problems.^[4]
