Proof step 45 from proof bitsand-cast-04 (previous step)

false ' + bits0 ≠ [] ∧ false ' + bits1 ≠ [], # bits1 ≤ # bits0 + n0, # bits0 < # bits1 ⊦ sgn(bitsand(false ' + bits1, false ' + bits0)) = sgn(bitsand(bits1, false ' + bits0)), n0 = 0, bits1 = []

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Rule argument

Additional information

Used simplifier rules: ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ boolvar ' + bits ≠ [];
