1. Often assume that the characteristics of the independent distribution of the same, then the likelihood function is often the form of liancheng, directly to cheat to the bad, according to log can be connected to add.2. Another probability value is a decimal, multiple decimals multiplied easily zhao floating point overflow, go to log into a plus can avoid this problem.If there is no connection in the original likelihood function, then go to the post-operative no log (a+b) Form, at this time can

The main reason is that the teacher used different methods to calculate the natural logarithm and understand the characteristics of different parallel languages. So I used multithreading. After OpenMP, I want to use opencl to implement the following. First I will introduce the algorithm. Method 1.

[Discrete logarithm] ultraviolet A 11916 Emoogle Grid Question: Apply K colors to an M * N matrix. There are B cells that cannot be colored, and each cell cannot be the same color as the cell above. If N and total result R are known, find the row M with the minimum satisfaction. All data has a modulo value of 100,000,007. Ideas: Because the X coordinates of the input vertex that cannot be colored must be within M. So record maxX. Divide the entire mat

An array in all languages, C is the simplest, is a starting address, plus the length of an array, and basically does not have any function to say. However, in the use of all arrays, it is a simple array of C, which is surprisingly flexible and
