Optimization Strategies

This section presents strategies for overcoming several challenges you might experience while using the optimizer.

Challenge #1: Infeasibility

It is easy to unknowingly constrain the vertical alignment so that it is infeasible. This is a difficult problem to diagnose in general, but several tools are provided to help you, including: Conflict Detection, Feasibility Tests, Softening, and the Vertical Band. These are covered in the first sub-article HERE.

Challenge #2: Speed and Accuracy

Optimization can take a long time. It is not difficult to generate problems which take hours (or even days --- yes really!). Unfortunately, there is no way to know in advance how long a specific problem will take. Recommendations for handling speed and accuracy are handled HERE.
