Possible network mutations. a Mutating the binary gene: The binary schema of a gene can be mutated by changing a ‘0’ to a ‘1’ (or vice versa) in the nodes string. b, c Adding or deleting nodes: Nodes can be added or deleted by altering the number of columns and rows in the adjacency matrix. New nodes are given random functionality/binary strings. d, e Adding or deleting connections: Connections within the network can be added or deleted by changing ‘0’s and ‘1’s in the adjacency matrix. f Moving connections: Connections can be moved in the network by swapping bits within the adjacency matrix
