QUESTION
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

Copying a VkImage that is being used to render to an offscreen framebuffer gives a black image.
When using a rasterizer the rendered image is non-empty but as soon as I switch to ray tracing the output image is empty:

Answered 2021-Jun-06 at 09:08Resolved by now:
When submitting the command buffer to the queue it would require an additional vkQueueWaitIdle(m_queue) since ray tracing finishes with a certain latency

I'm trying to import a Vulkan semaphore for using by CUDA on the windows platform, but always get a cudaErrorInvalidValue error. I can’t figure out what causes the problem.
Considering I have already a HANDLE for the Vulkan semaphore object, the Cuda side is at DLL1 as follows:

Answered 2021-May-20 at 16:11Object types are SQL types so they cannot be c reated in PL/SQL. You can, however, define a record type in a package rather than an object type and you should be able to use that record type to define a pipelined table function

I have the below function and I would like to turn it into a procedure. What would be the changes I need to accomplish it? I would like to turn it into a procedure because it's kind of a one purpose use function, and I would prefer to have it inside my main package along with my other procedures.
I would like to, instead of returning the table, creating it inside the procedure itself.
...ANSWER
Answered 2021-May-19 at 21:00A package can contain both procedures and functions.
There is no need to convert this from a function to a procedure to include it in a package.

QUESTION
I have a function -please find a MRE at the end of the question-, which assigns, by partition of pc and order by r, if 'ay' is not null, that 'ay', if an has any values, then those values cannot be picked. However, I'm struggling to understand how the below part works (namely how, if cur.ay is not null, then the assigned a is ay). I would also need to enhance this function to include also logic for a column 'ao' which, if possible then assigned to that 'a', but, if cur.c<=0, try to assign it to any of the available 'a's. Could someone clarify how the logic in the loop works so I can try to enhance the logic myself?

The script below takes one string input as a polyline and returns a data frame with the corresponding latitude/longitude pairs.
I would like to input to be a data set as follows:
ActivityID Polyline 1 PolyLineValue1 2 PolyLineValue2 3 PolyLineValue2and the output to be (keeping the ActivityID)
ActivityID latitude longitude 1 123 123 1 123 123 1 123 123 2 123 123 2 123 123 2 123 123 3 123 123 3 123 123 3 123 123I was thinking along the lines of iterating over the input dataset to do this but I've read here that's not a great idea performance wise.
Please can someone advice how to do this in Python?
