There are two integers: $A, B$. Given the below four allowed operations (and only them):

$A+1$, $A-1$, $\sqrt{A}$, $A^2$

Also, it is only allows to take the square root of $A$ when this square root yields a natural number.

How can one find the minimum amount of operations in order to get from $A$ to $B$?

How can one find the minimum amount of operations in order to get from $A$ to $B$?

There're two integers $A$ and $B$. Only with four operation below:

$A+1$, $A-1$, $\sqrt{A}$, $A^2$

How to count minimum numbers of 'operation' above needed to change $A$ to $B$?
