Lecture 3

How to solve the graph?

1. Solve all constraints and plot
2. Solve for the objective function and slide parallel until feasible area is met.

Unique Solutions, Multiple Solutions, Unbounded Solutions, Infeasible Solutions

Unique Solutions

NB: The parallel objective function to touch on the point farthest from Origin for Maximisation / nearest to Origin for Minimisation.

Multiple Solutions

NB: Alongside the entire line at the edge of the feasible area.

Unbounded Solutions

Solution towards infinity…

Infeasible Solutions

No feasible area…
