kandi X-RAY | resolution Summary
This is the R implementation of an algorithm to find communities in networks with resolution parameter based on the article "Laplacian dynamics and Multiscale Modular Structure in Networks" R. Lambiotte et al. The algorithm in the function cluster_resolution detects clusters using stability as an objective function to be optimised in order to find the best partition of network. The number of clusters typically decreases as the resolution parameter (t) grows, from a partition of one-node communities which are as many as nodes when t = 0 to a two-way partition as t grows. Because of fact that the result of the algorithm depends on the order in which the nodes are considered, we have introduced the parameter RandomOrder. When RandomOrder is NULL the order of vertices come from the graph, if is FALSE vertices will be arranged in alphabetical order, and if is TRUE vertices will be arrange in random order. In the case of a choice random order you can set the number of repetitions (rep patameter) and then the best solution (which will have the highest value of modularity) among these repetitions will be returned. In order to receive all outcomes from random orders it has been created cluster_resolution_RandomOrderFULL function which returns four-element list containing: table with each outcome, modularity for each outcome, the best clustering (partition which has the highest value of modularity), the value of modularity fot the best clustering.

QUESTION
I am having trouble resolving a ReDoS vulnerability identified by npm audit. My application has a nested sub-dependency ansi-html that is vulnerable to attack, but unfortunately, it seems that the maintainers have gone AWOL. As you can see in the comments section of that Github issue, to get around this problem, the community has made a fork of the repo called ansi-html-community located here, which addresses this vulnerability.
Thus, I would like to replace all nested references of ansi-html with ansi-html-community.
My normal strategy of using npm-force-resolutions does not seem to be able to override nested sub-dependencies with a different package altogether but rather only the same packages that are a different version number. I have researched this for several hours, but unfortunately, the only way I have found to fix this would appear to be with yarn, which I am now seriously considering using instead of npm. However, this is not ideal as our entire CI/CD pipeline is configured to use npm.
Does anyone know of any other way to accomplish nested sub-dependency package substitution/resolution without having to switch over to using yarn?
Related QuestionsThese are questions of interest that I was able to find, but unfortunately, they tend to only discuss methods to override package version number, not the package itself.

Answered 2021-Oct-29 at 21:01I figured it out. As of October 2021, the solution using npm-force-resolutions is actually very similar to how you would specify it using yarn. You just need to provide a link to the tarball where you would normally specify the overriding version number. Your resolutions section of package.json should look like this:
QUESTION
This code sample fails to compile due to ambiguous overload resolution
...ANSWER
Answered 2022-Mar-30 at 06:35The second overload is more specialized than the first one during partial ordering of function templates.
According to [temp.deduct.partial]/5 the reference on T &t of the first overload is ignored during template argument deduction performed for partial ordering. The following paragraphs distinguish based on reference/value category only if both parameters are reference types.
Then T of the first overload can always deduce against a type A* invented from the parameter of the second overload, but T* of the second overload can't deduce against a type A invented from the parameter of the first overload.
Therefore the second overload is more specialized and is chosen.
With T (&t)[4] argument deduction in both directions will fail because deduction of T[4] against A* will fail and so will deduction of T* against A[4]. Array-to-pointer decay of the array type is specified for template argument deduction for a function call but not for template argument deduction for partial ordering. See also active CWG issue 402.
So neither template will be more specialized in this case and the partial ordering tiebreaker does not apply.
The array-to-pointer conversion is not relevant. It is not considered any worse than the identity conversion sequence (see [over.ics.rank]/3.2.1 excluding lvalue transformations which array-to-pointer conversions are).
QUESTION
This works and outputs "1", because the function's constraints are partially ordered and the most constrained overload wins:
...ANSWER
Answered 2022-Mar-29 at 18:45C++20 recognizes that there can be different spellings of the same effective requirements. So the standard defines two concepts: "equivalent" and "functionally equivalent".
True "equivalence" is based on satisfying the ODR (one-definition rule):
Two expressions involving template parameters are considered equivalent if two function definitions containing the expressions would satisfy the one-definition rule, except that the tokens used to name the template parameters may differ as long as a token used to name a template parameter in one expression is replaced by another token that names the same template parameter in the other expression.
There's more to it, but that's not an issue here.
Equivalence for template heads includes that all constraint expressions are equivalent (template headers include constraints).
Functional equivalence is (usually) about the results of expressions being equal. For template heads, two template heads that are not ODR equivalent can be functionally equivalent:
Two template-heads are functionally equivalent if they accept and are satisfied by ([temp.constr.constr]) the same set of template argument lists.
That's based in part on the validity of the constraint expressions.
Your two template heads in versions 1 and 3 are not ODR equivalent, but they are functionally equivalent, as they both accept the same template parameters. And the behavior of that code will be different from its behavior if they were ODR equivalent. Therefore, this passage kicks in:
If the validity or meaning of the program depends on whether two constructs are equivalent, and they are functionally equivalent but not equivalent, the program is ill-formed, no diagnostic required.
As such, all of the compilers are equally right because your code is wrong. Obviously a compiler shouldn't straight-up crash (and that should be submitted as a bug), but "ill-formed, no diagnostic required" often carries with it unforeseen consequences.

I am currently setting up a boilerplate with React, Typescript, styled components, webpack etc. and I am getting an error when trying to run eslint:
Error: Must use import to load ES Module
Here is a more verbose version of the error:
...ANSWER
Answered 2022-Mar-15 at 16:08I think the problem is that you are trying to use the deprecated babel-eslint parser, last updated a year ago, which looks like it doesn't support ES6 modules. Updating to the latest parser seems to work, at least for simple linting.
So, do this:
- In package.json, update the line
"babel-eslint": "^10.0.2",to"@babel/eslint-parser": "^7.5.4",. This works with the code above but it may be better to use the latest version, which at the time of writing is 7.16.3. - Run
npm ifrom a terminal/command prompt in the folder - In .eslintrc, update the parser line
"parser": "babel-eslint",to"parser": "@babel/eslint-parser", - In .eslintrc, add
"requireConfigFile": false,to the parserOptions section (underneath"ecmaVersion": 8,) (I needed this or babel was looking for config files I don't have) - Run the command to lint a file
Then, for me with just your two configuration files, the error goes away and I get appropriate linting errors.

QUESTION
In following program, struct C has two constructors : one from std::initializer_list and the other from std::initializer_list. Then an object of the struct is created with C{{1}}:
ANSWER
Answered 2022-Feb-12 at 23:30The wording could be clearer (which is unsurprising), but GCC and MSVC are correct here: the relevant rule ([over.ics.list]/7) checks only that
overload resolution […] chooses a single best constructor […] to perform the initialization of an object of type
Xfrom the argument initializer list
so the fact that the initialization of B from {1} would be ill-formed is irrelevant.
There are several such places where implicit conversion sequences are more liberal than actual initialization, causing certain cases to be ambiguous even though some of the possibilities wouldn’t actually work. If the programmer was confused and thought one of those near misses was actually a better match, it’s a feature that the ambiguity is reported.

QUESTION
I am trying to understand overloading resolution in C++ through the books listed here. One such example that i wrote to clear my concepts whose output i am unable to understand is given below.
...ANSWER
Answered 2022-Jan-25 at 17:19Essentially, skipping over some stuff not relevant in this case, overload resolution is done to choose the user-defined conversion function to initialize the variable and (because there are no other differences between the conversion operators) the best viable one is chosen based on the rank of the standard conversion sequence required to convert the return value of to the variable's type.
The conversion int -> double is a floating-integral conversion, which has rank conversion.
The conversion float -> double is a floating-point promotion, which has rank promotion.
The rank promotion is better than the rank conversion, and so overload resolution will choose operator float as the best viable overload.
The conversion int -> long double is also a floating-integral conversion.
The conversion float -> long double is not a floating-point promotion (which only applies for conversion float -> double). It is instead a floating-point conversion which has rank conversion.
Both sequences now have the same standard conversion sequence rank and also none of the tie-breakers (which I won't go through) applies, so overload resolution is ambigious.
The conversion int -> bool is a boolean conversion which has rank conversion.
The conversion float -> bool is also a boolean conversion.
Therefore the same situation as above arises.
See https://en.cppreference.com/w/cpp/language/overload_resolution#Ranking_of_implicit_conversion_sequences and https://en.cppreference.com/w/cpp/language/implicit_conversion for a full list of the conversion categories and ranks.
Although it might seem that a conversion between floating-point types should be considered "better" than a conversion from integral to floating-point type, this is generally not the case.
