Proof step 36 from proof bitsand-cast-04 (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 37:
# bits0 < # bits1, # bits1 ≤ # bits0 + n0 ⊦ sgn(bitsand(mklist(false, n0) + false ' + bits0, false ' + bits1)) = sgn(bitsand(false ' + bits1, false ' + bits0)), n0 = 0, bits1 = []

Rule argument

Additional information

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