Looking at the past three years, Oct20 seems somehow similar to Nov17, another "findconstrainedalgorithm" challenge. Nov17 was actually solved by 23 people only. On the other hand, both Oct20 and July20 deal with linearrecurrenced sequences, candidate solutions can be analyzed with similar linear algebra methods. About CHAOS, I found it useful to know that the following kind of instruction is permitted: 30 CHAOS 30, 40, 50, ... so that the control flow graph has an edge from a oneline block to itself.

Had it been necessary, writing it would have been too spoiling. I only wrote that I found it useful (shorter code, faster reaching 1970)

Of course I can remove all "tricky" edges from my solutions; the easiest way requires to keep the same number of incoming/outcoming edges by adding suitable nodes as new sources/destinations, which means some more CHAOS lines. As an example, the length of my 7step bonus solution grows from 17 to 19, not a problem, but I judge the "tricky" version more efficient. So far, I found no "untricky" solutions which fit both the 6step and the 20line constraints.
