👉 Borstal, also known as a "bottleneck," is a concept in the field of computer science and artificial intelligence. It refers to a situation where a program or algorithm cannot find an element that meets certain criteria due to its size or complexity. In other words, if you have a large dataset with many elements, it may not be possible for your program to find all the necessary elements within a reasonable amount of time. Borstals are often encountered in machine learning and data mining applications
