The purpose of the matching idea is that perhaps this can be used in a fast way to generate inventions.
When looking at objects in our universe they are built of smaller matching objects. They belong to the bigger object, they match somehow. For organic objects you find that they match within the exterior and the object as a whole. My idea is that you can place a number on that property. A matching value.
The tool for this I imagine is something like a 3D heal section function for objects. You can try examples of the 2D heal function in GIMP (software) for images.
If you then take some size of the volume out of the object and heal that section using a 3D heal function. You will get a value how well they matched the rest of the object when comparing with the original big object. Then integrate that procedure over the whole object and you get a matching value.
