I came across a problemhere. I have two submissions here. The first onehereinvolves a queue(deque in Python) that is a BFS approach. The second onehereinvolves a stack that is a DFS approach. So I have a few questions here. What is the time complexity and space complexity of both the...

(ISAAC 2014), reconsidered classical fundamental graph algorithms focusing on improving the space complexity. Elmasry et al. gave, among others, implementations of breadth first search (BFS) and depth first search (DFS) in a graph on n vertices and m edges, taking O(m + n) time using O(...
STACS ( 2015), reconsidered classical fundamental graph algorithms focusing on improving the space complexity. Elmasry et al. gave, among others, an implementation of breadth first search ( BFS) in a graph G with n vertices and m edges, taking the optimal O( m+ n) time using O( n) ...
It does look like the BFS and DFS approach have the same time complexity and space complexity but if I have got that wrong, how do I know when to use DFS and when to use BFS particularly the grid questions involving number of components?(The editorial suggests any of DFS or BFS so sti...
But the complexity is simply too high. The two concepts Hierarchy and Abstraction are helpful to deal with the complexity. Hierarchy shows the structure of the design and the Abstraction hides the lower level details. This research mainly focuses the area of the Physical (or Layout) domain. ...

(ISAAC 2014), reconsidered classical fundamental graph algorithms focusing on improving the space complexity. We continue this line of work focusing on space. Our first result is a simple data structure that can maintain any subset $S$ of a universe of $n$ elements using $n+o(n)$ bits ...
