Re: [Taler] optimal coin spending example

    Hi Calvin,
      
      You might probably want to read the GNU Taler design documents
      about fee structure and metrics as
        first step into this matter:
        
https://docs.taler.net/design-documents/012-fee-schedule-metrics.html
        and https://docs.taler.net/design-documents/008-fees.html 
        
https://docs.taler.net/design-documents/012-fee-schedule-metrics.html#proposed-solution
        gives examples for solutions at two different abuse levels. So,
        'price' in this context is a notion that can be stretched. https://git.taler.net/wallet-core.git/tree/contrib/articles/spending.txt
      tries to wrap it up in an algorithm. 
      
      Hope this helps a bit.
      
      Cheers,
      Stefan
