====== Tempfile ======

----

The tempfile is written regularly during a simulation, depending on the [[algorithms:main|optimization algorithm]]. 
It always contains the potential with the currently lowest sum of squares.

The file can be used to plot the current potential to see if it contains some unwanted features.

====  Simulated Annealing  ====

Every time a new minimum in the sum of squares is discovered, the ''tempfile'' is written. 

====  Differential Evolution  ====

Same as Simulated Annealing, ''tempfile'' always contains the potential with the lowest sum of squares.

====  Powell's Least Squares  ====

Once every time the outer loop has successfully completed. This means after every line that is written 
to standard output the ''tempfile'' is written.
