Confused about XORing and addition modulo $2$
It's my understanding that when you XOR something, the result is the sum of the two numbers mod $2$. Why then does $4 \\oplus 2 = 6$ and not $0$? $4+2=6$, $6%2$ doesn't equal $6$. I …
Grammar for language L on {a, b} where L = {w|na(w)mod 3 = 0}
Dec 3, 2019 · Please edit the question instead of adding details in a comment. As you can see, formatting characters often make comments unreadable. Anyway, that regular expression is …
DFA for $L_1= {w: (n_a (w)+2n_b (w)) mod 3<2}$ and $L_2=\ {w: …
In Q.1 , if mod 3 was considered to yield 0,1,2, like $|n_a (w)–n_b (w))\text {mod 3}|>0$, then states $12$ and $02$ should also be final states. Right? Just like $01$ is specified as …

Create CFG and pushdown automaton for {ww} [duplicate]
I've been trying to make a CFG, a pushdown automaton and a regular expression for the language $\qquad L (M) = \ {ww : w \in \ {a, b\}^*, |w| \text { is even}\}$. I understand how the …
Relation between logspace-uniform circuits and P-uniform circuits
You're right that any logspace-uniform family of circuits has polynomial size, so this qualification doesn't seem to be necessary. On the other hand, the same is not true for P-uniform circuits, …

Feb 13, 2016 · My knowledge in Latin and etymology is very limited, but, 'modulus' is a Latin word, and the form 'modulus' is singular, nominative. 'moduli' is its plural form, again in the …
Does XNOR of three variable equals XOR of same three variables
Jan 29, 2018 · XOR is addition modulo 2, and XNOR computes the sum modulo 2 of its inputs and 1. Since $$ (x+y+1)+z+1 \equiv x+y+z \pmod {2}, $$ We see that XORing three variables …
