Sometimes a transfer that is only slightly lower (e.g. by 1 m/s or so) but much further in the future is selected, resulting in more time warping than necessary.
Describe the solution you'd like
Create a setting with units of m/s^2. Then when comparing transfers the total adjusted cost is the raw deltav + the time difference from now. This will weight transfers that occur sooner, in order to prevent a transfer that is only very slightly cheaper but much further in the future from taking precedence.
For example: impatience_factor = 5e-6 = 0.000005
Then if there are 2 transfers:
Current time: Y1 D1
Transfer 1 => Time Y2 D1 => Raw deltav: 1000 => Adjusted deltav: 1046
Transfer 1 => Time Y2 D1 => Raw deltav: 999 => Adjusted deltav: 1091
Describe alternatives you've considered
Use existing earliest_departure and search_duration setting to limit searches to windows. User can search within each window then select transfer using arbitrary criteria.
