Monte Carlo algorithm (this algorithm is also called random simulation algorithm, which is an algorithm to solve problems through computer simulation, and at the same time = you can check the correctness of your model through simulation, which is a necessary method in the competition).

Data fitting, parameter estimation, interpolation and other data processing algorithms (there are usually a lot of data to be processed in the competition, and the key to processing data lies in these algorithms, usually using Matlab as a tool).

Linear programming, integer programming, multivariate programming, quadratic programming and other planning problems (most of the problems in modeling competitions belong to optimization problems, and many times these problems can be described by mathematical programming algorithms, usually realized by Lindo and Lingo software).

circumference ratio

Use the Greek letter π (pronounced [pa? ]), which is a constant (approximately equal to 3. 14 1592653), is the ratio of circumference to diameter. It is an irrational number, that is, an infinite cycle decimal. In daily life, pi is usually expressed as 3. 14, which is used for approximate calculation. The fractional part 3. 14 1592653 is enough for general calculation. Even if engineers or physicists want to make more accurate calculations, they only need to take the values to a few hundred decimal places at best.
