Similarity heuristic - Wikipedia
problem solving heuristics that may or may not lead to a correct solution. Analogy heuristics apply proven solutions to new problems. Working backward discovers the steps to solving a problem by first defining the solution. In means-end analysis, the current state is compared to the desired state, and a series of steps are proposed to close the gap between the two. An algorithm is a strategy that always yields a correct solution. Obstacles to problem solving include functional fixedness, the inability to see new uses for familiar objects, and mental set, using a previously successful problem-solving strategy without determining whether it is appropriate for a new problem.

Problem analysis phase
The only analytical heuristic in Table (2) that can be used without specific information about objects and attributes is heuristic (#5), “a simple sketch”, which has been cast in the abstract in Fig. (13) using heuristic (#27). Thus we move on to the solution phase.
Conclusion of Part III
The problem-solving heuristics derived in Part II have been demonstrated for application in invention. It is shown that invention can be couched in terms of an unwanted effect. Consequently the problem definition and analysis heuristics of USIT are applicable without modification. The three major strategies for problem solving used in Part II, utilization, nullification, and elimination, constitute a thorough approach to problem solving. Each strategy contains other heuristics; such as, A-F-A links used in utilization. It is expected that individual problem solvers applying these three major strategies will bring into the process his or her favorite heuristics as sub sets of the three. The three strategies provide a simple and convenient overview of the problem-solving phase. In the process of solving the belt problem, without allowing filtering, some seemingly (at first sight) illogical results came to mind. This reflects the power of the metaphor of generic names – ambiguity.
