|
|
is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
|
||
|
|
in order to gradually find an acceptable rate.
|
||
|
|
The retries exponentially increase and stop increasing when a certain threshold is met.

* I would like to keep this library as small as possible.
