Dashboard Logout. We want to add them all together. We first divide the problem into 8 equal sub-problems. We do this by breaking the addition up into individual numbers.

Why do we break it down to individual numbers at stage 1? Why don't we just start from stage 2? Because while this list of numbers is even if the list was odd you would need to break it down to individual numbers to better handle it.

A divide and conquer algorithm tries to break a problem down into as many little chunks as possible since it is easier to solve with little chunks.

It does this with recursion. Recursion is when a function calls itself. It's a hard concept to understand if you've never heard of it before.

This page provides a good explanation. We open up the bigger one, and inside is a slightly smaller one.

Inside that one is another slightly small doll. Let's say, inside the last doll is a key. But we do not know how many dolls there are. How do we write a function that opens up the dolls until we find a key?

The function repeatedly calls itself until it finds a key, at which point it stops. The finding key point is called a break case or exit condition.

We always add a break case to a recursive function. If we didn't, it'd just be an infinite loop! Never ending. Computer scientists love recursion.

Because it's so hard for normal people to understand, we have a schadenfreude sensation watching people struggle. Haha just kidding!

We love recursion because it's used in maths all the time. Computer scientists are mathematicians first, coders second. Anything that brings code closer to real-life mathematics is good.

Not just because some people love maths, but because it makes it easier to implement. Need to calculate the Fibonacci numbers?

The maths equation for this is:. A natural recurrence in our formula! Instead of translating it into loops, we can just calculate it:. This is one of the reasons why functional programming is so cool.

Also, as you'll see throughout this article, recursion reads so much nicer than loops. And hey, maybe you can feel a little happier when your coworker doesn't understand recursion but you do ;.

If the problem is small, then solve it directly. Otherwise, divide the problem into smaller subsets of the same problem. Conquer the smaller problems by solving them recursively.

If the sub-problems are small enough, recursion is not needed and you can solve them directly. With the code from above, some important things to note.

The Divide part is also the recursion part. The conquer part is the recursion part too, but also the if statement. If the problem is small enough, we solve it directly by returning n.

We do this with the multiplication symbol. Eventually, we return the factorial of the number. It'll output 1, for those interested.

We'll explore how divide and conquer works in some famous algorithms, Merge Sort and the solution to the Towers of Hanoi. In this image, we break down the 8 numbers into separate digits.

Just like we did earlier. This does not mean that the player cannot choose who to ally with and who to fight, but there are certain limits, e.

Wars between evil factions and more frequently between good ones are indeed not unheard of, either through AI choices or through scripts.

Additionally the Clans of Enedwaith faction starts with neither allies nor enemies and can therefore choose sides freely.

Furthermore, factions can be classified according to culture. There are seven cultures in the game, as the following table shows.

That's also why we go down all the way to 1 and not 2. If the base case was 2, we would stop at the 2 numbers. If the length of the list n is larger than 1, then we divide the list and each sub-list by 2 until we get sub-lists of size 1.

Merge Sort is an example of a divide and conquer algorithm. Let's look at one more algorithm to understand how divide and conquer works.

The Towers of Hanoi is a mathematical problem which compromises 3 pegs and 3 discs. This problem is mostly used to teach recursion, but it has some real-world uses.

Each disc is a different size. We want to move all discs to peg C so that the largest is on the bottom, second largest on top of the largest, third largest smallest on top of all of them.

There are some rules to this game:. We want to use the smallest number of moves possible. If we have 1 disc, we only need to move it once.

The number of moves is a power of 2 minus 1. To solve the above example we want to store the smallest disc in a buffer peg 1 move.

See below for a gif on solving Tower of Hanoi with 3 pegs and 3 discs. We can generalise this problem. If there is an even number of pieces the first move is always into the middle.

If it is odd the first move is always to the other end. Notice that with step 1 we switch dest and source. We do not do this for step 3. The algorithm gets a little confusing with steps 1 and 3.

They both call the same function. This is where multi-threading comes in. You can run steps 1 and 3 on different threads - at the same time.

Since 2 is more than 1, we move it down one more level again. So far you've seen what the divide and conquer technique is. You should understand how it works and what code looks like.

Next, let's learn how to define an algorithm to a problem using divide and conquer. This part is the most important.

Once you know this, it'll be easier to create divide and conquer algorithms. Most of the time, the algorithms we design will be most similar to merge sort.

For example, working out the largest item of a list. Given a list of words, how many times does the letter "e" appear?

If we have an algorithm that is slow and we would like to speed it up, one of our first options is divide and conquer.

There isn't any obvious tell-tale signs other than "similar to a famous example". Now we know how divide and conquer algorithms work, we can build up our own solution.

In this example, we'll walk through how to build a solution to the Fibonacci numbers. We can find Fibonacci numbers in nature. The way rabbits produce is in the style of the Fibonacci numbers.

You have 2 rabbits that make 3, 3 rabbits make 5, 5 rabbits make 9 and so on. But by mathematicla definition, the first 2 numbers are 0 and 1.

Now the first thing when designing a divide and conquer algorithm is to design the recurrence. The recurrence always starts with a base case.

We can describe this relation using a recursion. A recurrence is an equation which defines a function in terms of its smaller inputs. Recurrence and recursion sound similar and are similar.

Or in other words:. But what if we don't have this list stored? How do we calculate the 6th number without creating a list at all?

Okay, what are those? Eventually we break it down to the basecases. Okay, so we know our code calls itself to calculate the Fibonacci numbers of the previous ones:.

Okay, how do we merge the Fibonacci numbers at the end? As we saw, it is the last number added to the current number. Now we've seen this, let's turn it into recursion using a recurrence.

Luckily for us, it's incredibly easy to go from a recurrence to code or from code to a recurrence, as they are both recurrences!

We often calculate the result of a recurrence using an execution tree. We saw this earlier when exploring how to build it in code.

For F 6 this looks like:. We ignore the addition for now. This results in 2 new nodes, 3 and 2. Same for 2. We do this until we get a bunch of nodes which are either 0 or 1.

This is no different from calculating the big o notation of our own algorithms. Once you've identified how to break a problem down into many smaller pieces, you can use concurrent programming to execute these pieces at the same time on different threads speeding up the whole algorithm.

Divide and conquer algorithms are one of the fastest and perhaps easiest ways to increase the speed of an algorithm and are useful in everyday programming.

Here are the most important topics we covered in this article:. The next step is to explore multi-threading. Choose your programming language of choice and Google, as an example, "Python multi-threading".

Figure out how it works and see if you can attack any problems in your own code from this new angle. You can also learn about how to solve recurrences finding out the asymptotic running time of a recurrence , which is the next article I'm going to write.

At least this isn't a pop up! In computer science, time complexity is the computational complexity that describes the amount of time it takes to run an algorithm.
