Formulation from Prose
Situations described in words, to be turned into variables, an objective and constraints. The descriptions vary in what they leave implicit, a unit that must be inferred, a restriction stated as a ratio, a quantity that sounds like a variable and is data, because reading the description is the part that does not transfer from worked examples.
What this involves
Retrieval after a delay, which is what makes knowledge durable.

What this covers
- Formulate a described decision problem as a linear program
Given a described resource-allocation or planning problem in prose, the learner can define decision variables with explicit units, write a linear objective, and write one linear constraint per stated restriction.
- Identify a described problem's shape and what it implies
Given a decision problem described in words, the learner can name its shape as covering, packing, allocation or a stated hybrid, justify the classification from the language of the description, state the direction of the objective and of the constraints that follow, and name the terminal outcome the shape makes most likely.
