Search Algorithms: Changes as of 12 March 2019

[norvig]

We've gone through several drafts of new algorithms for search. After some student-testing and comments from reviewers, we have a new version, as shown in aima4e-algorithms.pdf and in https://github.com/aimacode/aima-python/blob/master/search4e.ipynb

This version tested better than previous ones, so this is what we're going with, it will require some changes to the 3e version, and even to some work that some of you did earlier on changes to 4e. (Sorry to give you extra work.)

Hi Peter, please I'm happy to work on this challenge. On it.

[norvig]

Thank you @dyasem

You're welcome @norvig
Please I've also sent you an email expressing my interest in working on the implementation of the pseudocode algorithms in Java.

Hi Mr.Norvig.. I'm pleased to show interest in this challenge.. In addition, I'm interested in working on the implementation of the pseudocode algorithms in Python. I wish you get back to me soon

Hi Peter, I am interested to work on the challenge. It would be great working on the Python implementation of pseudo code algorithms. It would be great if you get back to me regarding the same.

Hi Peter, I would love to work on the challenge. I would like to discuss with you the implementation in Java.

am interested in this project, is there any pre=application form?

@norvig Please review pull requests #90, #91, and #92 regarding this issue.

@norvig where could I get examples for implementing the pseudocodes of aima4e in python. I asked this because sometimes it is difficult to figure out the type of data we're dealing with. For example, what is a percept(in terms of data type), what is the table of actions an array or hashtable and again what really actions are. Thanks in advance; any help would be appreciated.

I'm looking forward to help you out in this issue.

in the above gist I tried to code the first algorithm in aima/pseudocode/readme.md given here
https://github.com/aimacode/aima-pseudocode/blob/master/md/Table-Driven-Agent.md

so as of now I don't have to work on percept so leave it alone but in order to implement the hashtable I need to know how to use the array of percepts as a key to get a hash value for which I need to know what a percept is. Does that mean that we have to create a custom hashtable?
