- What are the common abbreviation for minimum in equations?
I'm searching for some symbol representing minimum that is commonly used in math equations
- What is the difference between minimum and infimum?
What is the difference between minimum and infimum? I have a great confusion about this
- Minimum Perimeter of a triangle - Mathematics Stack Exchange
I have been playing the app Euclidea, I have been doing quite well but this one has me stumped "Construct a triangle whose perimeter is the minimum possible whose vertices lie on two side of the
- Is the minimum cost edge in a cycle always in the MST?
As you’ve noted, this is False It’s a bit of a trick question because of your related facts In the above counterexample, 4 is the smallest edge in the 4,5,6 cycle, but it wouldn’t be included in the minimum spanning tree since the 1,2 path is shorter
- Must a minimum weight spanning tree for a graph contain the least . . .
Currently learning about spanning trees and using Kruskal's algorithm and I was wondering whether a minimum weight spanning tree of a weighted graph must contain one of the least weight edges of every vertex
- Determine if an edge appears in all Minimum Spanning Trees
While this approach solves the problem, I'm looking for a way to decide whether some edge must appear in all minimum spanning trees without finding the minimum spanning trees
- difference between minimal and minimum edge cuts.
It is the same difference between the notion of minimal elements and minimum in a set provided by an order relation, in your case the set is the set of edge cuts and the relation in the insiemistic inclusion In general, minimum implies minimal, the viveversa is false
- linear algebra - Setting the gradient to 0 gives a minimum . . .
In general, yes, setting the gradient to zero could be an extremum or inflection, etc However, with least squares, the problem is convex, and without getting lost in the details, when a problem is convex, necessary conditions become sufficent
