top20 | code examples of Top-20 | Learning library

I am doing a project for the OneMax algorithm and am having a problem with the crossover.

Throughout its iterations, I take the top 'division' of people and loop through them.

For even numbers i assign 5 odd number people who they will crossover with (i.e 0,4,8,12 & 16 all match with 1,2,3,5,7 & 9 and then 2,6,10,14,18 all match with 11, 13, 15, 17, 19). This is used in order to ensure there are no duplicates.

I then choose a random cross point and split the lists, then the lists are split and returned as 2 split lists for parent A & B, which can then be used to make child A and B.

My problem is the fact that after a few iterations, the population converge to be the exact same bitstring.

Any help would be greatly appreciated!

I have the following code:

I need to do something quite specific and i'm trying to do it the good way , especially i want it to be optimized .

So i have a DataFrame that look like this :

How can I increase the spacing between the grouped barplot I have that has 3 bars per category without losing the correct annotations behind the bars? I have tried some things but all to no avail. Code I have for the barplots:

I have a problem with the already built in CurrencyPipe from Angular. I have tried with following

I'm trying to correctly align the numbers and percentages in the barplots I'm making so that they're exactly after each bar, but having some troubles trying to do so. I want the: "number (%percentage)" to come exactly after each bar (very small space between). However, now in case of the upper ones (Top 200, 400) the number and percentage are already shifted more forwards than the bottom ones (Top1-50). So when I try to shift them the bottom ones lack behind the upper ones, resulting in not very aesthetically pleasing look. Is there a way to fix this?

I am using NASA Tensegrity Robot Toolkit simulator, which uses YAML to build the structure. i have validated my structure from https://codebeautify.org/yaml-validator.

It keeps throwing the error of bad conversion on my file while works fine on a pre-installed yaml structure.

This is the terminal window:

tensegribuntu@TensegritBuntu-VM:~/NTRTsim$ build/yamlbuilder/BuildModel resources/YamlStructures/BaseStructures/SuperBall.yaml Box Ground setup graphics tensegribuntu@TensegritBuntu-VM:~/NTRTsim$ build/yamlbuilder/BuildModel resources/YamlStructures/ZenStructures/30bar.yaml Box Ground setup graphics terminate called after throwing an instance of 'YAML::TypedBadConversion' what(): yaml-cpp: error at line 0, column 0: bad conversion Aborted (core dumped) tensegribuntu@TensegritBuntu-VM:~/NTRTsim$

Any ideas?

I'm using Express to create an endpoint so that I can access it with API calls. When I do the search the first time, everything works great, but if I do it again, I get the results from the previous time PLUS the results from the new search. How do I get the search results to reset each time?

Here is a link to the actual endpoint: (change out the word "covid" for any search term you like and if you do it atleast twice, you will see data from your last search displayed even after you have done a new search)

Thanks so much for any help you can offer!

This is the app.js file which calls the twitterRouter and with app.use creates the endpoint at /search/:searchTerm:

app.js

My code generates an input field that allows a user to enter a value to search for. Then when they click the Submit button, it causes displayMap to be true, so that when the MapDisplay component renders, it will trigger an API search via the Map component and return values that are then displayed on the map.

The problem is that this process only works once. When I click the button again, it does do something, I confirmed that it is getting the new value in the input box, but I can't seem to figure out how to get the map to be rendered again.

I've tried setting other variables in the this.setState to try to get it to know that it needs to render the component again, but I guess I'm missing something, because nothing works.

I'm fairly new to React, so any help you can offer would be greatly appreciated.

This is the MainSearchBar.js, where most of the work as described above is happening:
