            Answered 2021-Jun-10 at 18:30

            Yes, it is possible, although I wouldn't recommend it. You can use the following:

            • Set up a string with the LaTeX code include pstricks.
            • Call tex2image(..., packages = c("auto-pst-pdf", ...)) so that the LaTeX package {auto-pst-pdf} is used. This supports embedding pstricks in documents for the pdfLaTeX by calling LaTeX for the figure in the background.
            • Make sure tex2image() calls pdfLaTeX with the -shell-escape option so that pdfLaTeX is allowed to call LaTeX. This is relatively easy by using the R package tinytex.

            A worked example for this strategy is included below, it is called dist4.Rmd. If you copy the R/Markdown code to a file you can run:

            How to make this very complicated query from three connected models with Django ORM?
            Asked 2021-Jun-09 at 00:05

            Good day, everyone. Hope you're doing well. I'm a Django newbie, trying to learn the basics of RESTful development while helping in a small app project. We currently want some of our models to update accordingly based on the data we submit to them, by using the Django ORM and the fields that some of them share wih OneToMany relationsips. Currently, there's a really difficult query that I must do for one of my fields to update automatically given that filter. First, let me explain the models. This are not real, but a doppleganger that should work the same:

            First we have a Report model that is a teacher's report of a student:



            Answered 2021-Jun-04 at 02:06

            Without having an environment setup or really knowing exactly what you want out of the data. This is a good start.

            Generally speaking, the Django ORM is not great for these types of queries, and trying to use select_related or prefetches results in really complex and inefficient queries.

            I've found the best way to achieve these types of queries in Django is to break each piece of your puzzle down into a query that returns a "list" of ids that you can then use in a subquery.

            Android Studio, define a JAVA_HOME variable
            Asked 2021-Jun-08 at 11:06

            I saw a video on Youtube for enhancing the performance of Android Studio. I did and now I can't launch my Android Studio. Now it gives an error saying that "If you already have a 64-bit JDK installed, define a JAVA_HOME variable in Computer > System Properties > System Settings Environment Variables. Failed to create JVM. JVM Path C:\Program Files\Android\Android Studio\jre\jre"

            I searched the whole internet and tried every solution mentioned but I still get the "define JAVA_HOME variable" error. I tried both completely uninstalling the Android Studio with all files and related folders manually deleted but still get this error and Android Studio just won't simply run. I have exams in a few days and I have a lot to practice.


            I just removed the JAVA_HOME. I have both the JDK and JVM installed. I am just uninstalling and installing Android Studio at the moment.

            Did you tried to remove Java_Home? Java_Home Then try to start Android Studio. If there is still error, Try to uninstall JDK from programs.

            I would strongly recommend to install this in the texmf tree of your LaTeX installation. Then it is always found, no matter where you compile a LaTeX file.

            Alternatively, you can also specify it using the header argument in include_tikz() with the full absolute file path:

            How to avoid "! LaTeX Error: Environment axis undefined" when using include_tikz with pgfplots?
            Asked 2021-Jun-06 at 02:50

            I have successfully included in an R/exams .Rmd file several graphics made in TikZ. The same does not happen when I try to include a plot under pgfplots using include_tikz(). Whenever \begin {axis} and \end {axis} are included, beware of the error "! LaTeX Error: Environment axis undefined".

            In the RStudio console the legend appears: "This is pdfTeX, Version 3.14159265-2.6-1.40.21 (TeX Live 2020) (preloaded format = pdflatex) restricted \ write18 enabled.entering extended mode", even having enabled in TexStudio write-18. None of these messages appear when I include other TikZ graphs other than pgfplots.

            Any TikZ graph works when run in TexMaker or TexStudio, which indicates that it is not a problem of the absence of LaTeX libraries or packages.

            How does std::unordered_map actually use hash functions?
            Asked 2021-Jun-04 at 21:00

            It is not very clear to me how the standard std::unordered_map container uses hashing.

            I am pretty new to hashing, and right now I'm trying to pass my university data structure exams.

            I understand that if I have a collection of objects, I have to group their keys as random as possible by a criteria so that they lie as uniformly as possible in some buckets, and I can afterwards search/insert/delete in constant time by looking into the bucket associated with the hashed key (this is mainly what hashing with chaining does, correct me if I am wrong).

            But, how does std::unordered_map use hashing? How does it set a new (key, value) pair using hashing? I mean, I know that hashing will group the keys by some criteria, but it is not clear at all how it sets a new (key, value) pair using hashing.



            Answered 2021-Jun-04 at 21:00

            For most standard library containers, the answer would be: However it feels like, it's an implementation detail left up to the writer of the library.

            However, unordered_map is a little peculiar in that respect because it not only has to behave in a certain way, but it also has contraints applied to how it's implemented.

            From the standard: http://eel.is/c++draft/unord.req#general-9

            The elements of an unordered associative container are organized into buckets. Keys with the same hash code appear in the same bucket. The number of buckets is automatically increased as elements are added to an unordered associative container, so that the average number of elements per bucket is kept below a bound. Rehashing invalidates iterators, changes ordering between elements, and changes which buckets elements appear in, but does not invalidate pointers or references to elements. For unordered_­multiset and unordered_­multimap, rehashing preserves the relative ordering of equivalent elements.

            In short, the map has N buckets at any given time. The result of the hash function is used to pick a bucket by doing something along the lines of bucket_id = hash_value % N. If the buckets start to get too "full", the map will increase N, and reorganize its contents.

            How are things organized within a bucket is not really specified. It's typically a linked list.

            OptaPlanner: Is the "constraint match" associated with a score just a semantical thing?
            Asked 2021-Jun-03 at 09:20

            I have a question about OptaPlanner constraint stream API. Are the constraint matches only used to calculate the total score and are meant to help the user see how the score results, or is this information used to find a better solution?

            With "used to find a better solution" I mean the information is used to get the next move(s) in the local search phase.

            So does it matter which planning entity I penalize?

            Currently, I am working on an examination scheduler. One requirement is to distribute the exams of a single student optimally. The number of exams per student varies. Therefore, I wrote a cost function that gives a normalized value, indicating how well the student's exams are distributed.

            Let's say the examination schedule in the picture has costs of 80. Now, I need to break down this value to the individual exams. There are two different ways to do this:

            • Option A: Penalize each of the exams with 10 (10*8 = 80).
            • Option B: Penalize each exam according to its actual impact.=> Only the exams in the last week are penalized as the distribution of exams in week one and week two is fine.

            Obviously, option B is semantically correct. But does the choice of the option affect the solving process?



            Answered 2021-Jun-03 at 08:40

            The constraint matches are there to help explain the score to humans. They do not, in any way, affect how the solver moves or what solution you are going to get. In fact, ScoreManager has the capability to calculate constraint matches after the solver has already finished, or for a solution that's never even been through the solver before.

            (Note: constraint matching does affect performance, though. They slow everything down, due to all the object iteration and creation.)

            To your second question: Yes, it does matter which entity you penalize. In fact, you want to penalize every entity that breaks your constraints. Ideally it should be penalized more, if it breaks the constraints more than some other entity - this way, you get to avoid score traps.

            EDIT based on an edit to the question:

            In this case, since you want to achieve fairness per student, I suggest your constraint does not penalize the exam, but rather the student. Per student, group your exams and apply some fairness ConstraintCollector. If you do it like that, you will be able to create a per-student fairness function and use its value as your penalty.

            The OptaPlanner Tennis example shows one way of doing fairness. You may also be interested in a larger fairness discussion on the OptaPlanner blog.
