rbase | Platform abstraction and utility library | Game Engine library

The concept of the program is to create a sudoku puzzle that can then be solved via pygame. Where I got stuck is this error:

I am trying to convert the code by replacing for loop with while loop.
This is the code which I want to be converted

To solve the issue "java.lang.OutOfMemoryError: Java heap space" in R, you need to change global options as follows:

I have a data frame like:

I am new to Coq, and my primary interest is in using it to do simple real analysis problems. For a first exercise, I managed to bash through a proof that x^2+2x tends to 0 as x tends to 0. See code below.

This seems pretty clunky, and I would be interested in any general feedback on how to shorten this proof, or good practice for improving its readability. However, my main question is whether there are any Coq tactics for automating simple tasks involving the real numbers, along the lines of field and lra but better.

possible example 1: are there any tactics to prove identities for the functions from Rbasic_fun, such as the absolute value? For example, half my proof is dedicated to showing that |x*x|+|2*x|=|x||x|+2|x| !

possible example 2: are there any tactics to automate the use of the lemmas from Rineq, such as Rlt_le, Rle_trans, Rplus_le_compat_r and Rmult_le_compat_r? That is, lemmas that a human proof-creator would use to "chain together" a sequence of inequalities.

I'm using a pattern of assigning a base class to a templated class so that I can put different types in a vector, vis-a-vis Attribute and Attribute, and the reason for this is that I want a vector containing different objects that inherit the same base object.

The problem that I am getting of spurious text being generated relates to the output that is generated once the Base object is retrieved from the vector and cast back to the original Attribute template object.

Problem Output, using inline comments to show where output differed from expectation:

I want to get the 'BASE' number by 'svn info' command in Windows batch file as the following batch script:

I weren't surprised when found that I can use base-class pointers for usage to derived classes like this (very simple):

I am trying to include bibliographic citations and a list of references in a MS Word file generated with Rmarkdown bookdown. However, I get the following message in the RMarkdown terminal: “pandoc-citeproc: reference Rbase not found”, where Rbase is the id of the cited material.

Although the MS Word file is generated, the citation is not recognised as such in the introduction (instead it shows “[@Rbase]”, nor the list of references is displayed (see image attached).

This is my .Rmd file:
