How can I find the minimum cut on a graph using a maximum flow algorithm?

I need to find the minimum cut on a graph. I've been reading about flow networks, but all I can find are maximum flow algorithms such as Ford-Fulkerson, push-relabel, etc. Given the max flow-min cut theorem, is it possible to use one of those algorithms to find the minimum cut on a graph using a maximum flow algorithm? How? The best information I have found so far is that if I find "saturated" edges i.e. edges where flow equals capacity, those edges correspond to the minimum cut. Is that true? It doesn't sound 100% right to me. It is true that all edges on the minimum cut will be saturated,

Prolog, find minimum in a list

in short: How to find min value in a list? (thanks for the advise kaarel) long story: I have created a weighted graph in amzi prolog and given 2 nodes, I am able to retrieve a list of paths. However, I need to find the minimum value in this path but am unable to traverse the list to do this. May I please seek your advise on how to determine the minimum value in the list? my code currently looks like this: arc(1,2). arc(2,3). arc(3,4). arc(3,5). arc(3,6). arc(2,5). arc(5,6). arc(2,6). path(X,Z,A) :- (arc(X,Y),path(Y,Z,A1),A is A1+1;arc(X,Z), A is 1). thus, ' keying findall(Z,path(2,6,Z),L).' in

Is this minimalist HTML5 markup valid?

<!DOCTYPE html> <meta charset="utf-8"> <body> Hello, world! SOURCE FOR CODE If so, besides removing "Hello, world!" is there any tag that's able to be removed and it still be valid, and how do you know it's still valid? It's not valid. To check it you can run it in W3C Validator The error is: Element head is missing a required instance of child element title. ... UPDATE As vcsjones stated the head element is optional. That's the title one is required. Credit to mootinator for pointing out that the body is also optional. So the simplest valid document will be: <!DOCTYPE html> <title></title>

How can I find the minimum value in a map?

I have a map and I want to find the minimum value (right-hand side) in the map. Here is how I did it: bool compare(std::pair<std::string ,int> i, pair<std::string, int> j) { return i.second < j.second; } //////////////////////////////////////////////////// std::map<std::string, int> mymap; mymap["key1"] = 50; mymap["key2"] = 20; mymap["key3"] = 100; std::pair<char, int> min = *min_element(mymap.begin(), mymap.end(), compare); std::cout << "min " << min.second<< " " << std::endl; The code above works fine and I'm able to get the minimum value. However, when I put this code inside my class as

Numpy minimum in (row, column) format

How can I know the (row, column) index of the minimum of a numpy array/matrix? For example, if A = array([[1, 2], [3, 0]]) , I want to get (1, 1) Thanks! Use unravel_index : numpy.unravel_index(A.argmin(), A.shape) [Corrected typo] Another simple solution is ri, ci = A.argmin()//A.shape[1], A.argmin()%A.shape[1] As numpy.argmin returns the index reading in row-major order Yes, you are right, it was a typo, which worked for square matrix 来源： https://stackoverflow.com/questions/3230067/numpy-minimum-in-row-column-format

Java Minimum and Maximum values in Array

My code does not give errors, however it is not displaying the minimum and maximum values. The code is: Scanner input = new Scanner(System.in); int array[] = new int[10]; System.out.println("Enter the numbers now."); for (int i = 0; i < array.length; i++) { int next = input.nextInt(); // sentineil that will stop loop when 999 is entered if (next == 999) { break; } array[i] = next; // get biggest number getMaxValue(array); // get smallest number getMinValue(array); } System.out.println("These are the numbers you have entered."); printArray(array); // getting the maximum value public static int

Horizontal minimum and maximum using SSE

由 牧云@^-^@ 提交于 2019-11-27 16:17:02
问题 I have a function using SSE to do a lot of stuff, and the profiler shows me that the code portion I use to compute the horizontal minimum and maximum consumes most of the time. I have been using the following implementation for the minimum for instance: static inline int16_t hMin(__m128i buffer) { buffer = _mm_min_epi8(buffer, _mm_shuffle_epi8(buffer, m1)); buffer = _mm_min_epi8(buffer, _mm_shuffle_epi8(buffer, m2)); buffer = _mm_min_epi8(buffer, _mm_shuffle_epi8(buffer, m3)); buffer = _mm

C: Casting minimum 32-bit integer (-2147483648) to float gives positive number (2147483648.0)

I was working on an embedded project when I ran into something which I thought was strange behaviour. I managed to reproduce it on codepad (see below) to confirm, but don't have any other C compilers on my machine to try it on them. Scenario: I have a #define for the most negative value a 32-bit integer can hold, and then I try to use this to compare with a floating point value as shown below: #define INT32_MIN (-2147483648L) void main() { float myNumber = 0.0f; if(myNumber > INT32_MIN) { printf("Everything is OK"); } else { printf("The universe is broken!!"); } } Codepad link: http://codepad

Gnuplot: how to plot max and /or min value [closed]

问题 How can I show the max. and/or the min. value(s) of of a graph in a plot at their appropriate position automatically? 回答1: You can do this "semi-automatically" using the stats command. This command can extract some statistical values from a data set, but requires some reworking: Extract the minimum and maximum y-values, assuming that your data file has two columns, the x-value in the first, the y-values in the second column stats 'file.dat' using 2 nooutput name 'Y_' This gives you the min
