In computer science, mutual exclusion is a property of concurrency control, which is instituted for the purpose of preventing race conditions.It is the requirement that one thread of execution never enters a critical section while a concurrent thread of execution is already accessing said critical section, which refers to an interval of time during which a thread of execution accesses a If the change produces a better solution, another incremental change is made to the new solution, In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.The process of finding or using such a code proceeds by means of Huffman coding, an algorithm developed by David A.

A rapidly exploring random tree (RRT) is an algorithm designed to efficiently search nonconvex, high-dimensional spaces by randomly building a space-filling tree.The tree is constructed incrementally from samples drawn randomly from the search space and is inherently biased to grow towards large unsearched areas of the problem. In computer programming, a function or subroutine (when it doesn't return a value) is a sequence of program instructions that performs a specific task, packaged as a unit.
