Hamiltonian
A Hamiltonian is a mathematical function that describes a physical system's energy and how its energy changes over time. It is a key concept in studying systems in the physical world, including classical mechanics, quantum mechanics, and statistical mechanics.
In simpler terms, imagine a system as a box with a mass attached to a spring. The position of the box and the spring's length determine its energy. The Hamiltonian tells us how these quantities relate and how the energy changes as the system evolves over time.
Backtracking
Backtracking is a problem-solving technique that involves revisiting previous solutions to find a solution to a new problem. It's a key algorithm in algorithm design and analysis, and it's often used when dealing with complex problems that cannot be solved directly.
In the context of backtracking, we're looking for a solution to a problem by exploring all possible solutions we've already found. We can then use these solutions to guide us towards a solution for the current problem.
Example
Imagine you're searching for a specific solution to a maze puzzle. You've already solved similar puzzles, so you might try using those solutions as a guide to find the solution for the current puzzle. By revisiting the solutions you've already found, you can narrow down your search space and eventually find the solution
