Algorithm design Algorithm design. Algorithm design is a specific method to create a mathematical process in solving problems. Applied algorithm design is algorithm engineering. Algorithm design is identified and incorporated into many solution theories of operation research, such as dynamic programming and divide-and-conquer.

complexity When you see the word complexity, think of something with a lot of pieces, something not easy to put into words or understand. Things that can have complexity include: the events leading up to the American Civil War, a broth made with many ingredients, your relationship with your parents. Complexity is the opposite of simplicity. When something has a lot of complexity, you say it is complex. When it has very little complexity, it is simple.

Computational complexity theory Simpler complexity classes are defined by the following factors: 1  The type of computational problem: The most commonly used problems are decision problems. However, complexity classes can be defined based on function problems, counting problems, optimization problems, promise problems, etc.

Real-time computing Real-time computing. In computer science, real-time computing (RTC), or reactive computing describes hardware and software systems subject to a real-time constraint, for example from event to system response. Real-time programs must guarantee response within specified time constraints, often referred to as deadlines.

algorithm An algorithm (pronounced AL-go-rith-um) is a procedure or formula for solving a problem, based on conductiong a sequence of specified actions. A computer program can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem. Algorithms are widely used throughout all areas of IT (information technology). A search engine algorithm, for example, takes search strings of keywords and operators as input, searches its associated database for relevant web pages, and returns results.

Procedural generation Procedural generation. In computing, procedural generation is a method of creating data algorithmically as opposed to manually. In computer graphics, it is also called random generation and is commonly used to create textures and 3D models. In video games, it is used to automatically create large amounts of content in a game. Advantages of procedural generation include smaller file sizes, larger amounts of content, and randomness for less predictable gameplay.

- About 10% of all meniscal tears have a chance of healing. Of those 10%, only about 70-80% will actually eventually heal, even with surgical help. If a torn meniscus is not untreated, about 1-3% of knees may become asymptomatic. The other 97% of the meniscal tears will either not get better or will get worse.

Social complexity Current usage of the term complexity in the field of sociology typically refers specifically to theories of society as a complex adaptive system. However, social complexity and its emergent properties are central recurring themes throughout the historical development of social thought and the study of social change.

Introduction To program such a computer, in order that it will solve a certain problem or generate some desired result, the programmer first writes an algorithm, which is a solution of the problem in the form of a sequence of steps, written in ordinary language.he importance therefore of the Turing machine is its being the fundamental concept of any digital computer. We are now ready to describe a few Turing machines. A Turing machine computes a function. T(X) = Y, where X is some input and Y the output.
