OptimizationFuel
Description

Optimisation fuel is used to control the amount of work the optimiser does.

Every optimisation step consumes a certain amount of fuel and stops when it runs out of fuel. This can be used e.g. to debug optimiser bugs: Run the optimiser with varying amount of fuel to find out the exact number of steps where a bug is introduced in the output.
