2.Dynamic Programming, Greedy Algorithms[Coursera] This is a course that covers all the techniques for designing algorithms like divide and conquer dynamic programming and greedy algorithms. It will introduce you to features like intractability and NP-completeness. You will also get a basic understandi...
Greedy Algorithms vs Dynamic Programming Greedy Algorithmsare similar to dynamic programming in the sense that they are both tools for optimization. However, greedy algorithms look for locally optimum solutions or in other words, a greedy choice, in the hopes of finding a global optimum. Hence gree...

By greedy approach I mean, if(a > b) remove a square of (b x b) and proceed; else if(a < b) remove a square of (a x a) and proceed; else : we are done ! @[user:karthik8800]( or someone else ) can actually discuss ( elaborate ) , why this approach is wrong .. A cou...

Using Dynamic Programming approach with memoization: voidfib(){fibresult[0]=1;fibresult[1]=1;for(inti=2;i<n;i++)fibresult[i]=fibresult[i-1]+fibresult[i-2];} Are we using a different recurrence relation in the two codes? No. Are we doing anything different in the two code...
this approach can lead to a bias toward the first element. If you make this oversight, you might end up paying that bias, particularly if the optimal reward happens to be tied to the first arm (yes, I’ve been there). The Greedy approach is typically the least-performing one and we...
