You can also get inspiration from last spring's CS221 projects (student access only). Google has many special features to help you find exactly what you're looking for. A CSP is defined as a set of Variables and each variable has a finite set of possible values called its domain. Constraints differ from the common primitives of other programming languages in that they do not specify a step or sequence of steps to execute but rather the properties of a solution to be found. Langvillez Timothy D. Sudoku puzzle is a search problem in the sense that the agent explores the search space using a certain strategy until it reaches a goal state.

Solving a CSP means finding an assignment that satisfies all the constraints. Happy work. The search space is explored using Depth First Search(DFS) by sequential instantiation of variables by getting. Backtracking is an algorithmic-technique for solving problems recursively by trying to build a solution incrementally, one piece at a time, removing those solutions that fail to satisfy the constraints of the problem at any point of time (by time, here, is referred to the time elapsed till reaching any level of the search tree). These two functions take as input an initial Sudoku board, and construct and return a CSP model where for model 1 all constraints. Sudoku is commonly solved by brute-force methods,.
