In order for a surgical system to be efficient enough to perform an operation, one needs to keep in mind how the core of said system is developed.
Fault tolerance would be key to such a system. Fault tolerance would involve making sure such a system would have some sort of a backup in response to a hardware or software issue or failure. In a hospital setting, many things in relation to fault tolerance need to be considered. This goes well beyond standard backups for power in event of a power outage, but also hard coded fault tolerant mechanisms and backup hardware.
In relation to computation, cellular automata will play a large role in regards to space vectorization and surface area recognition. Computationally, a said program can only know to analyze what it can understand. You have different variations of chaotic and complex
CML systems when dealing with the brain. Various layers and components of the brain also have different layers and degrees of freedom. This is important given the regard to how accurate such a system needs to be.
