Proof step 12 from proof shiftzero-zero-size (previous step)

i < 0, i < 0 ⊦ j = 0, bits2int(sublist(0, # int2bits(i), mklist(false, i→n(j)) + int2bits(i))) = bits2int(sublist(0, #(false ' + int2bits(i)), mklist(false, i→n(j)) + false ' + int2bits(i)))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 13:
i < 0 ⊦ j = 0, bits2int(sublist(0, # int2bits(i), mklist(false, i→n(j)) + int2bits(i))) = bits2int(sublist(0, 1 + # int2bits(i), mklist(false, i→n(j)) + false ' + int2bits(i)))

Rule argument

Additional information

Used simplifier rules: ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ # boolvar ' = 0 +1;% ⊦ #(bits + bits0) = # bits + # bits0;
