Hello Community, Recently I gave a coding interview test at a company. This was one of the problem I was unable to solve. Can anyone please guide me through the approach and the solution. This was the problem statement :- Hydrate the nodesThere is a tree with n nodes. The tree is roo...
A clearcut solution to an urban tree problem.Sandfort, SteveBrash, SteveRimer, Julie
You are given a tree of n nodes rooted at1. Each node of the tree has a color associated with it. Now you are givenqqueries. In each query, you are given a node numberXand for each query, you have to mark the nodeXas special and all the other nodes in its subtree with the sam...
In early 1996, Arora [35] and Mitchell [289] gave PTAS’s for a class of geometric optimization problems in the plane, which included the TSP, Steiner tree, and k-MST. Both of these methods were based on methods of approximating an optimal solution with one that comes from a special cl...
A billion toothbrushes will be thrown away in the U.S. this year, most of them plastic. How did we get here, and can we change?
The objective function is not needed here, and might as well be a constant term 0. The problem is really just to find a feasible solution, meaning one that satisfies all the constraints. However, for tie breaking in the internals of the integer programming solver, giving increased solution sp...
Today I've listed some DP tutorials and problems. Actually, I made it for my personal practice. But I think It may Help others too. Update: I write stuffHerein Bengali. I probably have one or two basic DP tutorials too. If you understand Bengali, it may help. ...
We investigate the role convexity plays in the efficient solution to the Steiner tree problem. In general terms, we show that a Steiner tree problem is always computationally easier to solve when the points to be connected lie on the boundary of a convex region. For the Steiner tree problem ...
