QUESTION
In Julia JuMP, I am wondering whether it is possible to access an array, or similar, of the GAP history, the GAP improvements.
I know that at the end of the optimization, I can access the final gap with relative_gap(m) with m of type Model and I want the history of improvements over the solving process.
It could be for instance a vector of Float64 in percent: gaps=[20.2, 16.7, 13.8, 5.1, 0]. In such case my problem is solved to optimality as the final gap is 0.
At the end, I would like to plot the gap improvement in function of time of solving. So maybe all values of gaps could be a couple of two elements, the gap and the solving time until this new gap improvement?
Maybe this is not possible in JuMP so you could answer for Gurobi ?
Thanks!
...ANSWER
Answered 2022-Mar-01 at 21:48It's not possible using JuMP in general.
You could do this in Gurobi using a solver-specific callback: https://github.com/jump-dev/Gurobi.jl#callbacks
Or you could just parse the Gurobi log file that gets printed.
In general though, this information isn't all that useful as it can be quite noisy. Why do you want it?
QUESTION
I would like to have a grid layout on a page where the grid stretches out to the entire viewport, and the rows have a minimum height. The simplest example would be a grid with a single cell (see code snippet below).
The problem I am having is that when the height of the viewport is less than the defined minimum row-height, the row vertically overflows its container. With the added red and green borders in the below example it's visible that the row's height isn't going below the defined 500 pixels, but the grid-container is still sized to the viewport which is now shorter than 500 pixels.
If I remove the height CSS attribute from the grid class, the container doesn't shrink below its content, but it also doesn't fill out the vertical space when the viewport is taller than 500 pixels. Since I want the grid to fill the entire page, I need the height CSS attribute. I've also added the min-height: fit-content attribute which is supposed to prevent the used value of the height property from becoming smaller than the value specified for min-height but it doesn't work (not with the defined fit-content value - it works as expected with an exact value, for example 300px).
In a similar question the culprit was the percentage values used for the gaps, but in this case there is nothing relatively sized. Even if replace the grid-template-rows: minmax(500px, 1fr); property with the fixed grid-template-rows: 500px;, it still behaves the same way.
ANSWER
Answered 2022-Feb-05 at 08:28Something to know is that as soon as a min height of a row, or the combined height of multiple rows is grater than the height of the viewport, you would have a scroll. Beyond that, the snippet below I hope do what you are looking for. I added comments in the code.
QUESTION
On the news page of our website, we use Twitter's GET statuses/user_timeline API endpoint to pull in 4 tweets for every Ajax page of 8 news stories that we show, making 4 rows of 3 links in the results grid. This works fine for the first 8 pages (which takes us back just over a month from now in terms of tweets). But then when I get to the API call to fetch 36 tweets for page 9 and 40 tweets for page 10, it only returns 35 and 38 tweets.
I think this might be down to this issue that David Yell mentioned in his answer here, with the search API not returning tweets that it considers low quality or something. If I go to the timeline of our corporate Twitter account, I can see the specific tweets that are being omitted — I don'think they're necessarily spammy or low-quality, one has 47 interactions (21 RTs, 22 Likes and 4 replies) and another has 12 such interactions, so it's not like they're tweets that just went out echoing into the void, but sure, maybe the algorithm disagrees or whatever.
The API calls are effectively identical throughout; if I log the API call URL from my (bespoke C#) code involved and the number of tweets in the returned JSON, it is as simple as https://api.twitter.com/1.1/statuses/user_timeline.json?count=36&screen_name=[redacted]&exclude_replies=1&tweet_mode=extended returning only 35 tweets and …/statuses/user_timeline.json?count=40&… returning only 38, so it doesn't seem like there's anything wrong with the API calls per se, especially given the previous 8 calls all have the right number of tweets (so ?count=32… having 32 tweets in the JSON response and so on.) I know we have made more tweets since the QA analyst spotted this earlier in the week and the shape of the "missing" entries in the results grid has stayed consistent, but we hadn't got far enough in debugging until today to be able to confirm if it's the same tweets that were missing or not.
Does anyone have any experience of persuading the API to return those "missing" tweets? Or do I have to work out how to record and pass in the amended offset, to ensure I still end up with even pages of 4×3 in the results grid, without gaps? (Or something.)
...ANSWER
Answered 2022-Jan-22 at 14:47Some applications use count to fetch a number of entries and if the available amount is below then it fills null or returns an array short of the target number.
In this case, Twitter has detailed count means "best thought of as a limit to the number of Tweets to return because suspended or deleted content is removed after the count has been applied.".
Twitter also notes that the count includes retweets even if include_rts is not supplied.

QUESTION
How can I define a Doctrine property in a parent class and override the association in a class which extends the parent class? When using annotation, this was implemented by using AssociationOverride, however, I don't think they are available when using PHP 8 attributes
Why I want to:
I have a class AbstractTenantEntity whose purpose is to restrict access to data to a given Tenant (i.e. account, owner, etc) that owns the data, and any entity which extends this class will have tenant_id inserted into the database when created and all other requests will add the tenant_id to the WHERE clause. Tenant typically does not have collections of the various entities which extend AbstractTenantEntity, but a few do. When using annotations, I handled it by applying Doctrine's AssociationOverride annotation to the extended classes which should have a collection in Tenant, but I don't know how to accomplish this when using PHP 8 attributes?
My attempt described below was unsuccessful as I incorrectly thought that the annotation class would magically work with attributes if modified appropriately, but now I see other code must be able to apply the appropriate logic based on the attributes. As such, I abandoned this approach and just made the properties protected and duplicated them in the concrete class.

Sometimes there is a need to persist entities but override all or part of the mapping metadata. Sometimes also the mapping to override comes from entities using traits where the traits have mapping metadata. This tutorial explains how to override mapping metadata, i.e. attributes and associations metadata in particular. The example here shows the overriding of a class that uses a trait but is similar when extending a base class as shown at the end of this tutorial.
Suppose we have a class ExampleEntityWithOverride. This class uses trait ExampleTrait:

I have a problem with looking for gaps in my pandas dataframe.
So I have this data in my df:
date name score 2020-01-01 FEAT_1 0.64 2020-01-01 FEAT_2 0.17 2020-01-01 FEAT_3 0.09 2020-01-01 FEAT_4 0.07 2020-01-01 FEAT_5 0.03 2020-01-02 FEAT_1 0.90 2020-01-02 FEAT_2 0.30 2020-01-02 FEAT_3 0.20 2020-01-02 FEAT_4 0.10 2020-01-02 FEAT_6 0.02And what I want to do is to fill rows for dates that miss some FEAT_N. So, for example 2020-01-01 has feat1,2,3,4,5 but doesn't have feat_6 and I would like to put there new row with same date, feat_6 as name and score = 0. FEAT_N are .unique() values of column feature_name
I don't know how to deal with this problem. My main problem is that I don't know how to find if certain date in date column has FEAT_N value.

I am trying to write a JavaScript function that removes items from an array to reach a defined length. The function should eliminate the "gaps" evenly through the array. I need this function to simplify polygon vertices for canvas drawing.
This is how it should work:
This is the code I came up with:
...ANSWER
Answered 2021-Nov-27 at 22:43If you just want to eliminate items to cut that array to a desired length. Use the Array.splice() function.
So if your desiredLength = 3 for example. And you have an array = [1,2,3,4,5].
array.splice(0,desiredLength).length == desiredLength should be true.
QUESTION
I use this reverse-bit method of iteration for rendering tasks in one dimension, the goal being to iterate through an array with the bits of the iterator reversed so that instead of computing an array slowly from left to right the order is spread out. I use this for instance when rendering the graph of a 1D function, because this reversed bit iteration first computes values at well-spaced intervals a representative image appears only after a very small fraction of all the values are computed.
So after only a partial rendering we already have a good idea of how the final graph will look. Now I want to apply the same principle to 2D rendering, think raytracing and such, the idea is having a good overall view of the image being rendered even from an early stage. The problem is that making the same idea work as a 2D iteration isn't trivial.
Here's how I do it in 1D:
...ANSWER
Answered 2021-Nov-07 at 14:17Reversing the bits achieves the expected effect in 1D, you could combine this shuffling technique with another one where you get the x and y coordinates be selecting the even, resp. odd, bits of the resulting number. Combining both methods in a single shuffle is highly desirable to avoid costly bit twiddling operations.
You could also use Gray Codes to shuffle values with n significant bits into a pseudo random order. Here is a trivial function to produce gray codes:
