Algorithm to express every even number as sum of two prime numbers (Goldbachs conjecture)Pedro Garcia Pelaez
Addition, in mathematics, can be defined as the process of combining two or more numbers together to make a new total or sum. The numbers to be added together are calledaddendsand the result thus obtained is called thesum. What is subtraction? The process of finding the difference between ...
Let us take an example when n = 50. So we need to print all print numbers smaller than or equal to 50. We create a list of all numbers from 2 to 50. According to the algorithm we will mark all the numbers which are divisible by 2. Now we move to our next unmarked number 3 an...

When evaluating an approximation algorithm, one considers two measures: algorithm complexity and the quality of the answer (i.e., how close it is to being optimal). As in the case of complexity, the second measure may refer to the worst case or the average case. There are several categorie...
