  Speaker: Prof. Michael Sipser related_resources_text: '' transcript: >- [MATT BERG] [OK,] [so the] [problem is] [to write down a regular expression that] [matches all strings over the alphabet {0,] [1} with an odd number of zeros in them and an even number of ones in them,] [right?] [So let's see if we can think about this problem for a moment and see if we can get an intuition for what the regular expression might be like before we write it down explicitly.] [So it's important to keep in mind that we're working with regular expressions here so we're allowed to use operators like union,] [concatenation and Kleene star to build up our expression,] [and so it would be helpful to think about how we might use these operators to build up an expression that has the right properties that we want it to have.] [So let's, I guess the first thing to note is that there are some strings that we want our regular expression to match and there are some strings that we don't want our regular expression to match and so maybe it's useful to think about those two cases separately and see if we can come up with some sort of strategy for how to build up the expression using those two cases as building blocks.] [So one thing that's pretty clear is that any string with an odd number of zeros in it has to have at least one zero in it right?] [So one thing that we might try is to just add a zero onto the end of any string that has an even number of zeros in it so you could imagine doing something like this where you have an expression that matches any string with an even number of zeros in it,] [and then you just add another zero on, and this is where you could use concatenation right?] [You're saying take any string matched by this regular expression and concatenate another zero onto the end of it,] [and now you've got an odd number of zeros in your string right?] [So that would be one way, one strategy for coming up with strings that have an odd number of zeros in them. You could start with strings that have an even number of zeros in them and then just add another zero on the end of each one to make sure you get an odd number of zeros. Now there are also some things we know about ones right?] [We know for example that if you take any string with an even number of ones, say there are two ones in there,] [then if you take any string, any other string at all and concatenate those two together you're going to have an even number of ones in your new string right?] [Because adding more zeros won't change the fact that you've got two ones, so one thing we could do is take any string with an even number of ones in it and then concatenate another string onto the end, which doesn't have anything to do with ones at all really. It could be any old string. Doesn't matter as long as it doesn't change the fact that you've got an even number of ones in your original string. And so one thing you might try doing is taking strings with an even number of ones in them, and then concatenating some other string onto the end which has whatever property you want with respect to zeros. So you might try taking strings with an even number of ones in them, concatenating another string onto the end which has an odd number of zeros in it, or concatenating another string onto the end which has whatever property you want with respect to zeros. But since this particular problem only cares about whether or not you've got an odd or even number of zeros, and whether or not you've got an odd or even number of ones, then all you really care about is whether or not this other string has an odd or even number of zeros in it right? So I guess one way to approach this problem would be to say let's first think about what kind of regular expressions can we build up which match strings with only certain numbers of zeros or only certain numbers of ones in them. For example, can we build up a regular expression which matches strings with only even numbers of ones in them? Can we build up another regular expression which matches strings with only odd numbers of zeros in them? And once we've done that then maybe there's some way using union or concatenation or Kleene star that we can combine these two expressions into one single expression which matches all strings which have both properties right? So let's think about how we might go about building up these subexpressions first. How would we go about building up something like {0,1}*{11}*{0}*{11}*{0}*{11}*? Well one thing you could try doing is starting out by matching any old string at all. So maybe start out by matching anything over {0,1}*, match any old string at all, but then I guess what I'm trying to do here is I'm trying to guarantee by adding these things onto the end that I've got exactly two ones at the end right? Because I start out by matching any old string at all over {0,1}*, but then I add on two more ones using {11}*, then I add on some zeroes using {0}*. And so now I've got two more ones than I started out with. But now if I add on three more pairs of ones using {11}*{0}*{11}*{0}*{11}* then now I'm adding on six more ones than I started out with right? And six is even so whatever was my parity when I started out will remain unchanged after adding these six more pairs of ones right? So if I started out with an even number of ones adding six more will still give me an even number of ones, and if I started out with an odd number adding six more will still give me an odd number right? So maybe what I can try doing is starting out by matching any old string at all over {0,1}*, but then just making sure that from there on out I always add on pairs of ones whenever I need to add more ones into my strings. And so maybe what I can try doing is starting out by matching any old string at all over {0,1}*, but then just making sure from there on out whenever I add more ones into my strings they come along in pairs like this using {11}*{0}*. And so maybe what my regular expression could look like is something like this where I start out by matching any old string at all over {0,1}*, but then from there on out whenever I need to add more ones into my strings they always come along as pairs using {11}*{0}*. And so what happens when I add more than one pair like this? Well if I start out by matching any old string at all over {0,1}*, but then from there on out whenever I need to add more ones into my strings they always come along as pairs using {11}*{0}*, well maybe my final regular expression could look like this where from there on out whenever I need to add more pairs into my strings they always come along as pairs using {11}*{0}* repeated as many times as necessary using Kleene star right? So this looks pretty promising because now no matter how many times through this loop goes here adding pairs onto my strings will always leave me with either the same parity as when I started or else switch parity depending upon whether or not my initial parity was odd or even right? Because if my initial parity was even adding another pair won't change anything so will leave me still having an even parity afterwards, but if my initial parity was odd adding another pair will change my parity from being odd initially to being even afterwards right? So now let's think about what happens when I start out by matching some particular kind of string over here instead of just matching anything at all over here. So let's say instead of starting off by matching anything at all over here starting off by matching some particular kind of string over here say something like this where instead what happens is when my initial parity is even instead instead instead instead instead instead instead instead instead instead instead instead instead instead instead instead instead *** Transcript: *** <|file_sep|>> **MATT BERG** OK, so today's problem set focuses on asymptotic notation again. That was last week's topic. I'll give you guys a brief overview again. And hopefully today's problems should help solidify your understanding. So asymptotic notation allows us to talk about functions without having precise numerical values. It allows us give precise bounds on functions. And asymptotic notation lets us describe how fast functions grow. So asymptotic notation describes classes rather than individual functions. For example, logarithms grow slower than
