Morpho Design Explorer - GA Client

This is the GA Client Component of the Morpho Design Explorer Project. This client provides the GASearch class interface to connect to a MorphoDesignExplorer backend, load project schemas and existing generated models, and generate new children with custom fitness functions.

Sample usage is as follows:

# Import the search interface class
from morpho_ga import GASearch

# Define the server location URL and the project identifier for the project to operate on
SERVER_URL, project_id = "server_url_here", "project_id here"

# build the search interface and load generated models from SERVER_URL
search_object = GASearch(SERVER_URL, project_id)

# generate a child with the following fitness function: 2 <= step < 7
print(search_object.generate_child((Q.step >= 2) & (Q.step < 7)))

# get auth token from the server; will trigger a CLI prompt for a username, password and OTP
search_object.get_token()

# dump all generated models to the server in bulk
search_object.put_records()

The generate_child() method generates one child at a time. This offers great flexibility in generating a varying number of children with different fitness functions. An example is given below to demonstrate the same:

iterations = 0
unique = 0
while True:
    if unique == 10:
        break
    if unique < 5:
        # generate 5 children with random genes, from the pool with `step` > 0
        child = search_object.generate_child(Q.step > 0, parent_count=0)
    elif unique >= 5:
        # generate 5 more random chilren with genes crossed over from 2 parents, with 2 <= step < 7
        child = search_object.generate_child((Q.step >= 2) & (Q.step < 7), parent_count=0)
    if child is not None:
        # bump unique if child is not a duplicate
        unique += 1
    iterations += 1

search_object.put_records()

Todo

• Don't upload the entire set of records on generation of each child; only upload new children.
• Fetch username and password from a file and Fetch OTP from the CLI or through a CLI option.
• Detect and report malformed Server URLs passed.
