Ill-defined problems = don"t have their goals, starting information, or steps clearly spelled out: you don"t know what information you should start from, whether you have reached the goal or what rules apply (e. g. writing an important letter) Generate-and-test technique: consists of, generating possible solutions and then testing them, testing if those possibilities met all the criteria. Loses its effectiveness very rapidly when there are many possibilities and when there is no particular guidance for the generation process: can be useful when there aren"t a lot of possibilities to keep track of. Involves comparing the goal with the starting point, thinking of possible ways of overcoming the difference and choosing the best one: selected option may have certain prerequisite conditions.
