Proof step 14 from proof fill-sgn (previous step)

(# bits0)+1 = #(mklist(boolvar, n) + sgn(boolvar ' + bits0)), boolvar ' + bits0 = mklist(boolvar, n) + sgn(boolvar ' + bits0), # sgn(boolvar ' + bits0) ≤ 1 + # bits0 ⊦ mklist(boolvar, 1 + # bits0 - # sgn(boolvar ' + bits0)) + sgn(boolvar ' + bits0) = boolvar ' + bits0, ¬ boolvar ∈ sgn(boolvar ' + bits0) ∧ n = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Rule argument

Additional information

Used simplifier rules: ⊦ m + n = n + m;% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ # mklist(boolvar, n) = n;% ⊦ #(bits + bits0) = # bits + # bits0;% ⊦ m +1 = m + 1;
