Linear programming, also abbreviated as LP, is a simple method that is used to depict complicated real-world relationships by using a linear function. The elements in the mathematical model so obtained have a linear relationship with each other. Linear programming is used to perform linear optimization so as to achieve the best outcome.The reason why GTSAM needs to perform non-linear optimization is because the odometry factors f 1 (x 1, x 2; o 1) and f 2 (x 2, x 3; o 2) are non-linear, as they involve the orientation of the robot.

In this case the original problem is infeasible.Optimization is the process of finding the minimum (or maximum) value of a set of data or a function. This can be accomplished by analyzing extensive amounts of data and selecting the minimum (or maximum) value, but this is generally not practical. Instead, optimization is generally performed mathematically.5.3 Linear Functions, Convexity, and Concavity. Proposition 5.5 A linear function f (x) = aT x + b is both convex and concave. Proposition 5.6 If f (x) is both convex and concave, then f (x) is a linear function. These properties are illustrated in Figure 6.
