Accumulate - add the Value each frame.
Highest - if the value on the current frame is higher than this value then we keep it.
Lowest - if the value on the current frame is lower than this value then we keep it.
Fade Mode - determine whether values should remain persistent or fade back to the initial value.
Off - don't fade values.
Multiply by Value - on each frame, multiply values based on the Fade Value.
Fade Value - the speed at which the value will return to its initial values once the Solver is 'off' (e.g. outside a Falloff). The lower the value, the quicker the fade.
Offset - add/subtract a value to the output.
Start Frame -
Time - a default connection to the Composition's time attribute.
