vp | Very simple VideoPlayer | Crawler library

I am new to zimpl and I am currently trying to modell the GTSP. The setting is that we have nodes which are grouped into clusters. My problem is i dont know how to implement in zimpl which node belongs to which cluster.

What I did so far:

set V:= {1..6}; set A:= { in V*V with i < j};
set C:= {1,2,3};
set W:= { in C*C with p < q};
set P[]:= powerset(C); set K:= indexset(P);

I am guessing something is missing because i want to group node 1,2 in cluster 1, 3,4 in cluster 2 and 5,6 in cluster 3.

Some background Information:

Let G = (V, A) be a graph where V=1,2,...,n is the set of nodes and A = {(i, j): i, j ∈ V, i ≠ j} is the set of directed arcs (or edges), and let c_ij be the travel distance (or cost or time) from node i to node j. Let V1, V2, ... , Vk be disjoint subsets of V such that union of these subsets equals to V. These subsets are called clusters. The GTSP is to find the tour that (i) starts from a node and visits exactly one node from each cluster and turns back to the starting node (ii) never visit a node more than once and (iii) has the minimum total tour length. Associated with each arc, let x_ij be a binary variable equal to “1” if the traveler goes from node i to node j, and “0” otherwise.

Thats the mathematicl model I want to model: min∑i∈V ∑j∈V\{i} cijxij subject to: ∑i∈Vp ∑j∈V\Vp xij = 1 (p= 1, ..., k) ∑i∈V\Vp ∑j∈Vp xij = 1 (p= 1, ..., k) ∑j∈V\{i} xji − ∑j∈V\{i} xij = 0 (∀i∈V) xij∈{0,1} ∀(i, j)A up−uq+k ∑i∈Vp ∑j∈Vq xij+(k−2)∑i∈Vq ∑j∈Vp xij ≤ k−1 (p≠q;p,q=2,...,k) up≥0 (p=2, ..., k) (Thats the link for the paper: http://www.wseas.us/e-library/conferences/2012/Vouliagmeni/MMAS/MMAS-09.pdf)

Maybe someone can help! thanks

I'm trying to filter lines for a big txt file (around 10GB) bashed on prefix of called number only when the direction column equals 2.

This is the format of the file that i'm getting from pipe (from a different script)

I have been trying to pass a mat4 into VS. I am activating the shader program before passing the data:

I have this date-time stamp:

The idea is to draw the bounding box as 2D corners on the screen after my DiretXTK model is displayed.

I got the bounding box corners form DirectXKT in a std::vector, so

I'm trying to import a text file into R which has several columns separated by |. Here is the first line:

C00088591|N|M3|P|15970306895|15|IND|BURCH, MARY K.|FALLS CHURCH|VA|220424511|NORTHROP GRUMMAN|VP PROGRAM MANAGEMENT|02132015|500||2A8EE0688413416FA735|998834|||4032020151240885624

I used read.table to read the data:

pc <- read.table(file = source(file.choose()), header = FALSE, sep = "|")

However I get this error message when I execute the code above:

Error in source(file.choose()) : /Users/na/Desktop/Thesis/04_Data/Campaign contributions/indiv16/by_date/itcont_2016_10151005_20150726.txt:1:42: unexpected ',' 1: C00088591|N|M3|P|15970306895|15|IND|BURCH, ^

I went ahead and erased the commas in the dataset but it didn't work either:

Error in source(file.choose()) : /Users/na/Desktop/itcont_2016_10151005_20150726 copy.txt:1:43: unexpected symbol 1: C00088591|N|M3|P|15970306895|15|IND|BURCH MARY ^

Is it because there are multiple words in a column? How could I fix this?

I'm trying to project a texture on a simple cube meshFilter using only C# but I'm having a bit of a hard time understanding what to do. I almost got it working for the X axis rotation and there is a lot of bad warping for Y/Z. Basically, I update the UVs when the position/rotation of the camera changes, here is my code :

I have a TreeGrid with 2 component columns. The first component column contains a HorizontalLayout with a Label and a Button. The second component column contains a HorizontalLayout with a Button. I was not able to right align the Button in the first component column. Is it doable? If it is not doable, do you have any workaround suggestions? My constraints are the TreeGrid, the 2 columns and that the first column should contain a Label and a right aligned Button. What i tried so far

I want to run reduce to get an object with two properties based on the option property in the input objects. Please check my code below and expected output below:
