7.5 Multivariable Searches


Local Search Space

A topographical map shows the relationship between search parameters and cost values.



Figure 1.35 Local searches

Global Search space. In this case the system becomes 'stuck' in a local mimina.



Figure 1.36 Global searches

Global Search space. In this case the system searches all maxim.

7.5.1 Algorithms

The search algorithms change system parameters and try to lower system parameters.

The main question is how to change the system paramters to minimize the system value.

7.5.2 Random Walk

7.5.3 Gradient Decent

7.5.4 Simplex
