Code Ninjas is a for-profit educational organization specializing in teaching coding to kids, and is the largest kids coding franchise in the world with over 400 locations open and operating in three countries. [1] It is headquartered in Pearland, Texas. [2] It was founded by David Graham in 2016, inspired by watching his son learn Tae Kwon Do. [3]
Robot in a wooden maze. A maze-solving algorithm is an automated method for solving a maze.The random mouse, wall follower, Pledge, and Trémaux's algorithms are designed to be used inside the maze by a traveler with no prior knowledge of the maze, whereas the dead-end filling and shortest path algorithms are designed to be used by a person or computer program that can see the whole maze at once.
The Kerplunk experiment was a stimulus and response experiment conducted on rats [1] and demonstrates the ability to turn voluntary motor responses into a conditioned response. [2] The purpose of the experiment was to get kinaesthetic feedback rather than guidance through external stimuli [ 3 ] through maze learning. [ 2 ]
Genetic variation, such as better peripheral vision, can make some rats “bright” and others “dull”, but does not determine their intelligence. [3] Nonetheless, Tryon’s famous rat-maze experiment demonstrated that the difference between rat performances was genetic since their environments were controlled and identical. [4]
An example of an experiment within a multiple T-maze was performed by allowing the rat to explore the multiple T-maze without a reward. After letting the rat roam, researchers restarted the maze again with a reward placed at the end of the maze. The rats with prior exposure to the maze were able to easily navigate through the maze to reach the ...
Next, Small wondered if new rats not exposed to the maze were able to learn it just as quickly. Using four new rats, Small found that there tended to be a "lead rat" that would complete the task of opening the door to find food, while the other rats crowded around the spot, demonstrating that they were imitating the lead rat's behavior.
Individual rats would rarely eat except in the company of other rats. As a result extreme population densities developed in the pen adopted for eating, leaving the others with sparse populations. In the experiments in which the behavioral sink developed, infant mortality ran as high as 96 percent among the most disoriented groups in the population.
The radial arm maze was designed by Olton and Samuelson in 1976 to measure spatial learning and memory in rats. [1] The original apparatus consists of eight equidistantly spaced arms, each about 4 feet long, and all radiating from a small circular central platform (later versions have used as few as three [ 2 ] and as many as 48 arms [ 3 ] ).
