kandi X-RAY | inner Summary
A MOLP is a linear program with more than one objective functions. The linear constraints are arranged in a matrix form with c columns and r rows. Columns correspond to variables x1, x2, . . . , xc, which are subject to the restrictions. The lower bound Li can be -∞ and the upper bound can be +∞. For each row 1 ≤ j ≤ r the j-th constraint is. A feasible solution is a tuple x = which satisfies all constraints. There are m ≥ 1 objectives, which are given as. The m-dimensional objective vector y = is achievable if there is a feasible solution x which yields exactly these objective values. The solution of a MOLP is the list of all extremal objective vectors. For a minimizing (maximizing) MOLP the objective vector y is extremal if there is no other achievable objective vector y' which would be coordinatewise ≤ y (or ≥ when maximizing). The task of MOLP solver is to find the collection of all extremal objective vectors. These extremal vectors are called vertices as they form the vertices of an (unbounded) convex m-dimensional polytope. This MOLP solver finds the extremal vectors by iterations. In each step one more extremal vector is added to the final list. The time required for an iteration varies widely from a couple of microseconds to several days. After each iteration the solver checks if the process has been interrupted by a SIGUSR1 signal. If it has, it switches to a quick and dirty method which might find further extremal vectors (but not necessarily all of them). The linear constraints must have a feasible solution. Moreover, in a minimizing MOLP all objectives must be bounded from below, and in a maximizing MOLP all objectives must be bounded from above. The algorithm is described in details in the paper Inner approximation algorithm for solving linear multiobjective optimization problems, available at The program is invoked as. The only obligatory argument is the file name which contains the description of the problem in vlp format. Accepted options are. Fine tuning the algorithm and the underlying scalar LP solver, and specifying the amount and type of information saved is done by giving values of several keywords. Each keyword has a default value, which is overwritten by the values in the config file (if specified), and those values are overwritten by the --KEYWORD=value command line options. Change tolerances with great care.

QUESTION
I'm writing a Firebase function (Gist) which
Queries a realtime database ref (events) in the following fashion:
await admin.database().ref('/events_geo').once('value').then(snapshots => {Iterates through all the events
snapshots.forEach(snapshot => {Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event
await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {Data is prepared for SendGrid and the processing is finished
All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:

I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.
So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?
Best regards, Simon

I'm trying to make custom valueboxes in R Shiny. I've discovered how to change the color of the background, but something is making my value boxes stubby and leaving large gaps in between them. I'd like to display 3 on a line ideally, but even with a width of 4, they appear squished. How can I get them to have more of the red with just a small gap of white in between.

QUESTION
I am writing code to answer the following LeetCode question:
Given the head of a linked list and an integer
Example 1 ...val, remove all the nodes of the linked list that hasNode.val == val, and return the new head
ANSWER
Answered 2021-Jun-15 at 10:52Some issues in your code (as it was first posted):
return skipper(prev,curr)is going to exit the loop, but there might be more nodes to be removed further down the list.skipperonly takes care of a sub sequence consisting of the same value, but it will not look beyond that. The list is not necessarily sorted, so the occurrences of the value are not necessarily grouped together.Be aware that the variable
previnskipperis not the same variable as the other, outerprev. So the assignmentprev=currinskipperis quite uselessUnless the list starts with the searched value,
dummy.nextwill always remainNone, which is what the function returns. You should initialisedummyso it links toheadas its next node. In your updated code you took care of this, but it is done in an obscure way (in theelsepart).dummyshould just be initialised as the head of the whole list, so it is like any other node.
In your updated code, there some other problems as well:
while prev.next:risks to be an infinite loop, because it continues whileprevis not the very last node, but it also doesn't move forward in that list if its value is not equal to the searched value.
I would suggest doing this without the skipper function. Your main loop can just deal with the cases where current.val == val, one by one.
Here is the corrected code:

I have multiple currency based orders in database. When I was trying select order statistics, MySQL SUM not calculating same values.
For example I have same prices on two orders 2550 but sum calculating only one order and if I'll change one order price to 2551 it's working correctly.

Answered 2021-Jun-15 at 07:22You are doing SUM(distinct(IF(EUR.amount>0 ... which is summing only distinct values (I guess, I didn't know there was such an option). Use SUM(IF(EUR.amount>0 ... instead
