QUESTION
This question is an extension of my previous question: Fast python algorithm to find all possible partitions from a list of numbers that has subset sums equal to a ratio . I want to divide a list of numbers so that the ratios of subset sums equal to given values. The difference is now I have a long list of 200 numbers so that a enumeration is infeasible. Note that although there are of course same numbers in the list, every number is distinguishable.
...ANSWER
Answered 2021-Jun-12 at 15:14You can use a greedy heuristic where you generate each partition from num_gen
random permutations of the list. Each random permutation is partitioned into len(ratios)
contiguous sublists. The fact that the partition subsets are sublists of a permutation make enforcing the ratio condition very easy to do during sublist generation: as soon as the sum of the sublist we are currently building reaches one of the ratios, we "complete" the sublist, add it to the partition and start creating a new sublist. We can do this in one pass through the entire permutation, giving us the following algorithm of time complexity O(num_gen * len(lst))

QUESTION
I have my first Git repository that I have created online named myName/python-algorithms
.
It was containing many Python scripts. I tried to add a file test.py
from my local Ubuntu terminal with the commands:
ANSWER
Answered 2020-Feb-15 at 20:05So there are a few ways to fix an undesired commit. It looks like maybe your local git repo didn't have all the info in your remote repo, which caused your push to overwrite it. In your terminal, use git log to look at the commit history for your local git. If it only lists your test commit, we'll need to find the last good commit (where all the files still existed) a different way.
Go to your github and navigate to your commit history. You should see a commit prior to the last push "some init msg" that overwrote your other files. It will have a hex identifier (in blue) on the right. Copy it!
From your git terminal, you want to use the command: git checkout copiedhex#
This will copy to your local repo the version with all the files. However, you'll be in a detached HEAD state, and should get a message to that effect. You'll want to make this into a new branch by using: git checkout -b some_new_branch_name Then you can proceed as normal (merge it with master or keep working separately, push etc)

QUESTION
I am writing a small Python script to find time available slots based off calendar appointments. I was able to reuse the code on the post here: (Python - Algorithm find time slots).
It does seem to work for booked appointments an hour or longer, but for those less than an hour it doesn't seem to catch them. In other words, it shows time slots as available even though appointments are booked (less than an hou).
Sample code below from post mentioned, with my own values for "hours" and "appointments".

Install Python-algorithm
You can use Python-algorithm like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
