Introduction
The Crossover Symmetry packages include access to the Training Zone. The training includes in-depth videos and detailed instructions so you know exactly how and when to use each program based on your individual goals. In this tutorial I show you the simplest way to crack a coconut in half, and remove its flesh:) If you try this at home, please let me know how it works out.
Crossover and mutation are two basic operators of GA. Performance of GA very depends on them. Type and implementation of operators depends on encoding and also on a problem.

- JazzCat's answer works. Small addition: if your permissions are vague on.pem file, ssh-keygen will generate empty.pub file. If you see any complains on terminal about private key too open, try to narrow it using chmod 400 private.pem and retry above command. Ps: sorry I don't have permissions to add a comment instead of answer.
There are many ways how to do crossover and mutation. In this chapter are only some examples and suggestions how to do it for several encoding.
Binary Encoding
Crossover
Single point crossover11001011+11011111 = 11001111
Two point crossover - two crossover point are selected, binary string from beginning of chromosome to the first crossover point is copied from one parent, the part from the first to the second crossover point is copied from the second parent and the rest is copied from the first parent
11001011 + 11011111 = 11011111
Uniform crossover - bits are randomly copied from the first or from the second parent
11001011 + 11011101 = 11011111
Arithmetic crossover - some arithmetic operation is performed to make a new offspring
11001011 + 11011111 = 11001001 (AND)
Mutation
Bit inversion - selected bits are inverted11001001 => 10001001
Permutation Encoding
Crossover
Single point crossover - one crossover point is selected, till this point the permutation is copied from the first parent, then the second parent is scanned and if the number is not yet in the offspring it is addedNote: there are more ways how to produce the rest after crossover point
(1 2 3 4 5 6 7 8 9) + (4 5 3 6 8 9 7 2 1) = (1 2 3 4 5 6 8 9 7)
11001011+11011111 = 11001111
Two point crossover - two crossover point are selected, binary string from beginning of chromosome to the first crossover point is copied from one parent, the part from the first to the second crossover point is copied from the second parent and the rest is copied from the first parent
11001011 + 11011111 = 11011111
Uniform crossover - bits are randomly copied from the first or from the second parent
11001011 + 11011101 = 11011111
Arithmetic crossover - some arithmetic operation is performed to make a new offspring
11001011 + 11011111 = 11001001 (AND)
Mutation
Bit inversion - selected bits are inverted11001001 => 10001001
Permutation Encoding
Crossover
Single point crossover - one crossover point is selected, till this point the permutation is copied from the first parent, then the second parent is scanned and if the number is not yet in the offspring it is addedNote: there are more ways how to produce the rest after crossover point
(1 2 3 4 5 6 7 8 9) + (4 5 3 6 8 9 7 2 1) = (1 2 3 4 5 6 8 9 7)
Mutation
How To Open Keygen File
Order changing - two numbers are selected and exchanged
(1 2 3 4 5 6 8 9 7) => (1 8 3 4 5 6 2 9 7)
Value Encoding
Crossover
All crossovers from binary encoding can be used
Mutation
Adding a small number (for real value encoding) - to selected values is added (or subtracted) a small number
(1.29 5.68 2.864.11 5.55) => (1.29 5.68 2.734.22 5.55)
Tree Encoding
Crossover
Tree crossover - in both parent one crossover point is selected, parents are divided in that point and exchange part below crossover point to produce new offspring
