Jun 10, 2020 · But in showing a language is not RE, Turing reduction does not help, since it does not necessarily transfer RE-ness. For example observe that (Indeed, any language is Turing-reducible to …

K-Map Reduction Grouping Question I have a simple question regarding reduction using K-Maps. My professor gave this example: While I somewhat understand that we can only group quantities of base …

The intuitive notion of a reduction is "if I have an algorithm to solve problem X, then I can use it to solve problem Y, too". That's very intuitive -- but it maps much better to Turing reductions than to Karp …

May 19, 2022 · On the other hand, f f is a mapping reduction from ATM A T M to ETM¯ ¯¯¯¯¯¯¯¯¯ E T M, if we let f f map any string not of the form M, w M, w to Mloop M loop , where Mloop M loop is a …

This is a problem from Sipser's book (marked with an asterisk). EQTM = {( M , N ) where M and N are Turing machines and L(M) = L(N)} We know that neither EQTM nor ¯ EQTM are recognizable so …

Here is a reduction from L L to its complement: map 0 0 to 1 1 and everything else to 0 0.

Apr 25, 2020 · I was trying to solve a problem with a mapping reduction from $A_ {TM}$ to $INFINITE_ {TM}$, and came across a solution that was 100% identical to another solution I saw for $A_ {TM} …

You should provide context and define your notation (⇔ ⇔, → →, ≤m ≤ m). But if you are using common notations (⇔ ⇔ is logical equivalence, → → is implication, and the setting is classical logic) …

The reduction algorithm needs to do something specific with each "feature" of the X-instance; the portion of the output for each "feature" is usually called a gadget. But what's a feature? That depends on …
