Achess-playing computer program that routinely calculates all possible outcomes of all possible game moves best illustrates problem solving by means of:
a) an algorithm.
b) the availability heuristic.
c) functional fixedness.
d) belief perseverance.

An algorithm

Explanation: Computer programs are algorithms. They are finite set of rules or instructions carefully written to perform a specific task. The algorithm is written in a flexible manner without the moves being 'hard-coded', This allows the program to adjust and routinely calculate all possible game moves.

Hard coding the moves reduces the flexibility of the algorithm. Hard coding is used when there is something we want to embed within our program permanently without being changed.

The algorithm only states the rules of the game, without the limiting the moves a player can make.

another answer from our community: let us first explain the meaning of "eternal truth" which is tomean, continuing forever or indefinitely. this being the case itcannot be changed, for truth is truth no matter what changes aremade to the structure of its explanation. however, as for religeons changin… (more)
