Formula for Sequential Sub-Problem Solving

A problem-solving system is designed to break down a large initial problem ($p_0$) into a series of smaller steps. The process for generating the i-th step ($p_i$) is described by the formula: $p_i = G_i(p_0, \{p_{<i}, a_{<i}\}$) where $\{p_{<i}, a_{<i}\}$ represents all the preceding steps and their solutions. What does this formula imply about the system's approach to breaking down the problem?

Analyzing Problem Decomposition Strategies

A problem-solving process is defined by the formula $p_i = G_i(p_0, \{p_{<i}, a_{<i}\}$), where $p_i$ is the i-th sub-problem, $p_0$ is the original problem, and $\{p_{<i}, a_{<i}\}$ represents the set of all preceding sub-problems and their answers. This formula implies that all sub-problems can be determined and generated in a single step before any of them are solved.
