Perform a model-free optimisation using Dasha.
dir: The directory to place the files.
force: A flag which if set to True will cause the results file to be overwritten if it already exists.
binary: The name of the executable Dasha program file.
Dasha will be executed as
[numbers=none] $ dasha < dasha_script | tee dasha_results
If you would like to use a different Dasha executable file, change the binary name to the appropriate file name. If the file is not located within the environment's path, include the full path in front of the binary file name.
