How to optimize brainf*ck instructions

I'm trying to write an optimisation feature for my brainf*ck interpreter. It basically combines same instructions into 1 instruction.

I wrote this function but It doesn't work properly:

First off, just to rain a little on your parade I just want to point out that Wilfred already made a brainf*ck compiler in Rust that can compile to a native binary through LLVM (bfc). If you are getting stuck, you may want to check his implementation to see how he does it. If you ignore the LLVM part, it isn't too difficult to read through and he has a good approach.

When broken down into its core components, this problem revolves around merging two elements together. The most elegant way I have come across to solve this is use an iterator with a merge function. I wrote an example of what I imagine that would look like below. I shortened some of the variable names since they were a bit long but the general idea is the same. The merge function has a very simple job. When given two elements, attempt to merge them into a single new element. The iterator then handles putting them through that function and returning items once they can no longer be merged. A sort of optional fold if you will.

Format the result of as.numeric(x) with sprintf to obtain a two-digit group head for proper ordering: sprintf('%02.0f', as.numeric(2)) produces "02" which is then placed before "10" as desired.

On a sidenote: taking advantage of {dplyr}s functions can save a lot of work. E.g. calculating the mean for a selection of variables can be as concise as this:

Error while installing flask-mysqldb on ubuntu 20.04

Asked 2022-Feb-19 at 17:41

I am building a flask project and I want to use MySQL database. I need flask-mysqldb as an ORM for that. So as a good practice, I created a virtual environment, install flask and other dependencies, and then for installing flask-mysqldb, I used pip install flask-mysqldb. This suddenly gives me bunch of errors. At first I realized, I dont have MySQL installed on my system. So even after installing it these errors won't go away. I also tried pip install Flask-MySQLdb don't know how this is different from the first command but same errors.

I tried searching for errors online regarding flask-mysqldb, but most of them relate to some mysql.h file error which doesn't show in my terminal logs.

QUESTION

My Loop of the Loop is painstakingly slow

Asked 2022-Feb-10 at 02:15

I have an object $Posts which contain a title, and a SimTitles field amongst a few others. I need to compare each title to the other titles and give it a Similarity score in the SimTitles field. So if I have 80 $Posts, it will need to cover 6400 re-iterations as each title needs to be scored vs the others.

Apart from the Measure-TitleSimilarity routine which I believe is optimized, can anyone see a way to improve the speed of this double loop that I am missing?

Edit: I have included the function Measure-TitleSimilarity. I am actually passing the array to the function. The whole topic of quantifying arrays for likeness is fascinating. I have tried with Title.ToCharArray() which changes the magic number to a much higher number. It also can produce a match with two completely different titles as long as the characters are the same. (Ex: 'Mother Teresa' would closely match 'Earthmovers' or 'Thermometer' yet clearly not the same meaning). Cosine Similarity if just one method but it seemed easiest to process. @Mclayton and @bryancook - I see the light with your suggestion, but can't grasp tracking what no longer needs to be looked at for similar words.

ANSWER

Answered 2022-Feb-06 at 03:47

you can half the processing time by removing duplicate comparisons. I.e. once you compared "title1" and "title2", you don't need to compare "title2" and "title1" - you already know the answer. So, your inner loop should not start from the beginning of the array
