• The repository is structured language-wise i.e. algorithms in a certain language go in a specific folder.
• The naming convention to be followed is algo_name.language_extention i.e. the overall path should be language/algo_name.language_extention
• It is your choice to include only the function or the entire program for the algorithm.
• If the folder for your language does not exist, create a new one.

Hi there,

Thank you for your interest in Hacktoberfest and in helping others make their first contributions to open source.

While we agree that it's important to help others, this repository does not do this in a way that is in line with the Hacktoberfest values. Please read the part that talks about high-quality contributions to understand why we are reaching out and taking action. Due to this, we've added this repository to the list of excluded repositories which means pull requests here will not count toward Hacktoberfest 2020.

This is not a DigitalOcean decision, it's one that is inspired by the community of maintainers and contributors who all agree that quality is more important than quantity when it comes to engagement in the Open Source community. The values remind us to shift the focus from contributions to repositories that encourage folks to quickly create and gain a pull request to contributions that will help people level-up their skills and contribute to open-source projects that are in need of help.

If you feel that this repository is an effective learning resource, we encourage you to keep running it since a core part of the aim for Hacktoberfest is to encourage new folks to get involved with open-source.

However, if you are interested in having contributions to this repo count toward Hacktoberfest we encourage you to take a look at this list of Hacktoberfest issues for inspiration and make the necessary changes to focus on enabling people to make meaningful contributions to open source projects.

If you have any questions about this or participating in Hacktoberfest, please contact our team via email [email protected] or join our community Discord server.

Happy Hacking,
The Hacktoberfest Team

Hacktoberfest is presented by DigitalOcean, Intel and DEV.

Currently the files are in the form language/filename.
Change this to language/algorithms/filename for algorithms or language/ds/filename for data structures.

[Edit] Limit your changes to one or two languages.

We can create sub-folders in each language. It will make this task less confusing.
For starters, we can separate the codes into 'algorithms' and 'data structures'.

There's a './idea' in the repo. Please remove it.

I did a pull request but it did not count toward Hacktoberfest 2020

It's about time for hacktoberfest to start, is the repo accepting pull requests now ?

I made a C Implementation of a AVL : Self Balancing Tree

I want to add this Linked list program in python !! do please assign me !!

• Move 'remove_duplicates_cpp' from base folder into the cpp folder

Hello~

Thank you very much for sharing the code!

I try to use my own data set ( with the same shape as mnist) in code. After some iterations, it is found that the training loss became NAN. After carefully checking the code, I found that the following code may trigger NAN in loss:

In /python/algorithms/Classification Algorithms/MNIST Digit cassification using CNN.py: line 245

cross_entropy = tf.reduce_mean(-tf.reduce_sum(y_ * tf.log(y), reduction_indices=[1]))

If y contains 0 (output of softmax ), the result of tf.log(y) is inf because log(0) is illegal . And this may cause the result of loss to become NAN.

It could be fixed by making the following changes:

cross_entropy = tf.reduce_mean(-tf.reduce_sum(y_ * tf.log(y + 1e-8), reduction_indices=[1]))

or

cross_entropy = tf.reduce_mean(-tf.reduce_sum(y_ * tf.log(tf.clip_by_value(y,1e-8,1.0)), reduction_indices=[1]))

The same problem was also found at line 645:

cross_entropy = tf.reduce_mean(-tf.reduce_sum(y_ * tf.log(y_CNN), reduction_indices=[1]))

Hope to hear from you ~

Thanks in advance! : )
