SEED
Specifies the starting value the Fitter uses when randomly determining the initial placement for the current design. The value can be any non-negative integer value. Changing the starting value may or may not produce better fitting. Specify a starting value only if the Fitter is not meeting timing requirements by a small amount. The Design Space Explorer tool lets you sweep many seed values easily to find the best value for a given project. Modifying the design or Quartus settings even slightly will usually change which seed is best for the design.
