QUESTION
I've been attempting to create a node class which mimics a node on a graph. Currently, storage of the predecessor and successor nodes are stored via a node pointer vector: std::vector previous. The vectors for the predecessor/successor nodes are private variables and are accessible via setters/getters.
Currently, I am dealing with updating the pointer values when adding a new node. My current method to update the predecessor/successor nodes is through this method (the method is the same for successor/previous nodes, just name changes):

QUESTION
I am using a method to remove univariate outliers. This method only works if the vector contains outliers.
How is it possible to generalize this method to work also with vectors without outliers. I tried with ifelse without success.

I’d be grateful for suggestions as to how to remap letters in strings in a map-specified way.
Suppose, for instance, I want to change all As to Bs, all Bs to Ds, and all Ds to Fs. If I do it like this, it doesn’t do what I want since it applies the transformations successively:

QUESTION
I have the following piece of code in a shiny app. My goal is to generate the choices for the "cutFamily2" selectInput widget based on what the user chose for the "machine2" selectInput.
If I use corte2() instead of eval(paste0("corte",2)) on the observerEvent the app runs properly. The problem is that I want to use the paste0() because the integer "2" in eval(paste0("corte",2)) will be an argument of a function (function(data,n)) so I can easily generate corte1, corte2 and so on.
When I run it using eval(paste0("corte",2)) I am getting the "error in $: $ operator is invalid for atomic vectors" and the app won't even run. I tried to use enframe() to convert it to a tibble, then the app runs, but I get a "Unknown or uninitialised column: CutFamily" error and the SelectInput choices will be empty. I also tried [[ instead, but nothing.
Any ideas on how to solve the problem?

QUESTION
I made a Vector class. I was happy with it, it's kinda weird but it seemed to work at the start. But I just found out copying the vectors is impossible.
The reason is that to allow the number of coordinates to be a template, there is a templated variadic constructor which expects the right number of coordinates.
This is what it looks like, with the utility math methods removed:

I want to generate legend labels with code and use them as expressions because they contain greek letters and subscripts. However the same problem occurs with the title, and it is much easier to show, so I will use that in my example.

Answered 2021-Jun-15 at 08:05It might be preferable to create an expression instead of a character string.
If you want to turn a character string into an expression, you need to parse it:
QUESTION
I'm working on a system in Core to save the transforms of furniture, specifically position and rotation, which are both Vector3's. I have these in player storage, so at some point to save all the player's furniture, I think I will end up maxing out player storage. So I'm converting all the Vector3's to strings, with a modified version of a Roblox script that I found:
...ANSWER
Answered 2021-Mar-03 at 03:23Most likely the Vector3 format is more efficient than a string conversion for storage. Each number in the Vector3 requires 4 bytes to be stored because each number is a 16-bit float. By converting the Vector3 values to strings, additional bytes are required (each digit you add requires one byte since a character requires one byte). If you need to store a Vector3 as a string I would suggest using the method below.
For anyone who would like to learn how computers can store such a wide range of numbers in only four bytes, I would highly recommend researching the IEEE 754 format.
Video that explains the IEEE754 Format
You can use the string.pack and string.unpack functions to convert floats to byte arrays which can be sent as strings. This method will only require 12 bytes (12 characters) in total when sending data and has around 5 to 6 decimals points of precision. While this method may only save a few bytes it will allow you to send/save far more precise numbers/positions.

I'm trying to make a small simulation of traveling salesman in Unity C# and I can't get through this, my code looks right but start and nxtCity vectors always result in the same position, I really can't understand why, could any of you help?
cities is the number of total cities
positions is the array of cities taken from cities generator these two values are right in unity editor

Answered 2021-Jun-11 at 00:22Unity's Random.Range with (int, int) overload (NOT float, float) generates random number in range [min; max), max is exclusive, so if you call var randomInt = Random.Range(0, 1) result will be always 0. var randomInt = Random.Range(0, 2) would be 0 or 1, e.t.c
