In real world problems, the dominant situation is non-determinate i.e. it is likely that there is no solution that will fully satisfy the requirements. | |||
In such situations the basic, top-down, strategy is: propose a possible solution and assess whether it will be satisfactory - or more generally: identify a set of solutions and find the most appropriate one to use. This is the only feasible strategy for non-determinate contexts and may also be needed when the situation is determinate. | In such situations the basic, top-down, strategy is: propose a possible solution and assess whether it will be satisfactory - or more generally: identify a set of solutions and find the most appropriate one to use.
