Comments

Sums of triangle rows of the rule 30 automaton, in which the execution of the rule has been modified as such:

In the rule 30 CA, local cell neighborhoods are converted into a number 0-7, which is then used to determine if the central cell will be active in the next generation of the CA.

For this version, when determining this local neighborhood number, any positive nonzero value is treated as a Boolean TRUE. 0 values operate the same way as the conventional version of rule 30.

For example: [0],[0],[14] becomes [False],[False],[True] for the purposes of determining the local state.

Second, instead of writing a 1 when instructed by the 8 sub-rules, instead write the sum of the three local cells.
