real world problem solved by constraint satisfaction the previous sections dealt with creating constraint satisfaction problems nowlet us apply this to real world problems too some examples of real world problems solved by constraint satisfaction are as followssolving algebraic relation with the help of constraint satisfaction problemwe can solve algebraic relations in this examplewe will try to solve simple algebraic relation it will return the value of and within the range that we would define after completing this python programyou would be able to understand the basics of solving problems with constraint satisfaction note that before writing the programwe need to install python package called pythonconstraint you can install it with the help of the following commandpip install python-constraint the following steps show you python program for solving algebraic relation using constraint satisfactionimport the constraint package using the following commandfrom constraint import nowcreate an object of module named problem(as shown belowproblem problem(nowdefine variables note that here we have two variables and band we are defining as their rangewhich means we got the solution within first numbers problem addvariable(' 'range( )problem addvariable(' 'range( )nextdefine the particular constraint that we want to apply on this problem observe that here we are using the constraint * problem addconstraint(lambda aba =
