Thanks Razzle for your time and effort. This problem turns out to be NP Complete and the problem is basically Dominating Set Problem.

Hi,

Can anyone give an hint as to what is the underlying problem for this graph problem?

I think we need to sort the number of nodes...

Thanks nuzzle for thorough explanation. I actually implemented a greedy algorithm and it worked perfectly. Thanks for your time.

Hi,

If we are given an equation say 3x + 2y <= 10, we want to find the value of x and y such that

x + y = maximum and 10 - 3x - 2y is minimized. How can this be done? I am thinking of it as a...

Thanks nuzzle ! The O(n) algorithm I used is exactly same as yours. Thanks for your time.

Don't worry guys ! I found out the O (n) algorithm.

Hi,

I am trying to find a O (n) algorithm for this problem but unable to do so even after spending 3 - 4 hours. The brute force method times out (O (n^2)). I am confused as to how to do it ? Does...

Hi,

I have written an inefficient program for string matching. In this program we are suppose to tell whether it is possible to have all possible permutations of the first string (all distinct...

Hi,

I have written a program, in which it will ask the user to enter a string of length exactly 9. I have got a dictionary file with me which contains over two hundred thousand words. My job is to...
