I apologize if this question is out of the guidelines of this forum. If it is please let me know and I will abstain from requesting definitions and terminology.
Hello! I am currently writing a program to find the shortest path solution in a randomised Rubik's Cube. There is a certain language/search based methodology that has caught my attention, and which I would like to apply to the solution, but I am unaware of what kind of terminology I should be looking up.
The methodology is one where different languages are developed to satisfy different aspects of the cubes solution. For instance, we might find a language/grammar which appropriately describes/generates all transformations which move one block of the cube to some position we want it to be. We may then find another language which satisfies the movement of another block to some position we want it to be. The language which satisfies both of these languages is the one which generates transformations which will move BOTH blocks to where they are supposed to be.
WHAT I WOULD LIKE TO LEARN MORE ABOUT:
It is in this sense that I am interested in learning more about how languages can be tested against each other in order to CONSTRAIN the otherwise unweildly "search tree" that would be required to be derived and searched in order to find the solution.
At the same time I would like to build a symbolic vocabulary which would allow me to compare the different pertinent variables (runtime, memory size, etc.) of different tree search constraint methodologies, particularly language based methods (as I have poorly defined them).
I am also particularly interested in the methodologies that can be used to detect patterns in the strings which are satisfying two seperate languages so that a third language which satisfies both can be developed.
Also, I would like to learn more about how we can show that one language is mutually exclusive to another language.
I am particularly interested in terminology so that I might do research on the Internet, however I would also greatly appreciate any book recommendations. Thank You!
