Nico's parents are attempting to use a negative reinforcement technique embodied in the operant conditioning framework to increase Nico's studying.
Operant conditioning is a learning mechanism which consists on affecting the strength of a behaviour by reinforcement or punishment, depending if the aim is to increase or decrease it , respectively.
In this example, Nico's parents want him to acquire good studying habits, hence they allow him to quit from tasks he hates at home if he does so, for instance, doing the dishes. Hence, if he does not behave properly he will suffer the consequences and do the dishes. This a negative reinforcement as if the conduct is not appropiate, the response will be the obligation to do a task he hates.

Linear Programming is an optimization technique used in a system with multiple constraints that requires a solution. While not always optimal (even though it strives to be), the solution is at least feasible and adequate in managing limited resources in production, for example. LP will, in that sense, always have a single goal specified, trying to simplify a problem with multiple variables.
