Appendix Figure A8 | Consistent / inconsistent variable renaming example. This example shows
the original description that has variable names 𝑃, 𝑦, and 𝑡, along with versions with consistent and
inconsistent replacement. The original description’s variables are the blue variables in each triplet
[A][B][C], and similarly the consistent and inconsistent replacements are green (𝐴 replaced with
𝐵 everywhere) and red (𝐴 replaced with a random name 𝐶 independently for each appearance)
respectively. Consistent replacement does not change the problem, but random replacement introduces
noise and renders the problem ill-posed. Model deterioration with such modiﬁcations allows analysis
of how well a model captures the given variable structure. Problem sourced from Codeforces.
