kandi X-RAY | MC4 Summary
This project is all about implementing two of the most popular rank aggregation algorithms, Markov Chain Type 4 or MC4 and MCT. In the field of Machine Learning and many other scientific problems, several items are often needed to be ranked based on some criterion. However, different ranking schemes order the items based on different preference criteria. Hence the rankings produced by them may differ greatly. Therefore a rank aggregation technique is often used for combining the individual rank lists into a single aggregated ranking. Though there are many rank aggregation algorithms, MC4 and MCT are two of the most renowned ones.

QUESTION
I want to print code without \n on the result.
This is my code
ANSWER
Answered 2021-Aug-27 at 13:21I had this same problem and I got an answer here.
It's is because the line you read is always followed by a \n character. You need to remove it. Hence, just replace that last part of your code with this. .strip() will do for you. str(current_location).strip("\n")
Whenever you read a line from a text file, it adds a \n character to tell that new line started from there. You need to remove that while printing or it will mess up with your current statement
QUESTION
I have a series of identically formatted spreadsheets that I need to import into an access db. Unfortunately the spreadsheet data isn't in tabular form so I need to import a bunch of specific cells.
I read specific cells into variables and construct a query to insert rows into a table.
The code fails, when a cell contains a formula that equates to an error. To avoid the error, I must insert Null instead of the error value. How do I insert Null instead of the error value?
...ANSWER
Answered 2021-Sep-01 at 03:39Declare the variables as Variant to be able to assign Null to them. Then instead of quoting the values, when constructing the select statement, quote them before constructing it:
QUESTION
Suppose I have feature branch locally, FB. FB has diverged from master at commit, say CC. FB has several commits more, say FBC1,FBC2.FB is pushed to remote repository, and then merged into master. So remote master has FBC1,FBC2, and then few more commits prior and after.
Now if I pull remote commits to my local, so that my local master is now having CC-MC1-MC2-FBC1-FBC2-MC3-MC4, while FB has CC-FBC1-FBC2. So both master and FB have commits FBC1,FBC2.
Now if I rebase master on FB, then what would be behaviour?
...ANSWER
Answered 2021-Jul-06 at 13:57I don't think it would do anything because when you try to rebase a branch, git will try to find the last common ancestor between the branches involved... and at that point that revision is the tip of FB so git sees that there's nothing to rebase.

I need to load an SVG file into a Vue template. It must be loaded in such a way that I can access the internal classes with js and css, so presumably I'm looking for an The SVG is located on an external server, not a part of my project. Vue-Svg-Loader works just fine if I have the svg as part of my project, but doesn't seem to work when the SVG isn't available until runtime. I've tried the following tag and not an tag.

QUESTION
Here I'm designing a 16-bit CarrySelectAdder
Here is the adder file:
...ANSWER
Answered 2020-Mar-22 at 11:02The issue is that you tied the input port of your rippleCarryAdder instance to 0 instead of 1'b0.
0 is an unsized literal constant number here, meaning you did not define the bit-width of this constant. When looking at Section 5.7.1 (Integer literal constants) of the the SystemVerilog LRM, we find that:
The number of bits that make up an unsized number (which is a simple decimal number or a number with a base specifier but no size specification) shall be at least 32. Unsized unsigned literal constants where the high-order bit is unknown (X or x) or three-state (Z or z) shall be extended to the size of the expression containing the literal constant.
Hence, the compiler is interpreting your RTL as if you connected a 32-bit (or more) constant to the 1-bit input port of rippleCarryAdder.
QUESTION
I am coding a simple video game in adobe animate with as3. I am trying to move my objects through a swipe action through 3 different positions e.g:
...ANSWER
Answered 2020-Feb-26 at 20:56I cannot help you with gestures for I never worked with them directly, but positioning is logically... not difficult.
You have an Array of objects and an Array of positions. After the 1-st swipe you want only the first object go to the first given position:
QUESTION
I am using as3 in adobe animate to create a video game. I have created multiple arrays with movie clips e.g.
...ANSWER
Answered 2020-Feb-21 at 20:01There's no such thing as simultaneous in programming (well, unless you are multi-threading with the perfect sync, which is not an AS3 story at all).
There are to ways to get close to that simultaneous thing:
- Put all the objects into a single container. You will be able to change x and y of that container so all the in-laid objects will change their visible positions at once. The downside is that you cannot rotate or scale them individually (think of them as clipped to a board and imagine you rotate the whole board), or you won't be able to move half of them.
- Arrays and loops. You iterate through all the items one by one, very fast. It looks simultaneous from the outside, but it never is.
All that said, in order to achieve the things you want you need to figure a way to put all the objects you want to process simultaneously into a single Array and then do the thing you want on them.
Case №1: many Arrays to one.
