, an objective
and a strategy
. Metrics with a strategy of constraint
are given a threshold
. Metrics with a strategy of optimize
can optionally be assigned a threshold

, and constraint
respectively.Store
metrics are for tracking purposes. SigOpt can handle up to 50 stored metrics per training run or experiment.Optimize
metrics are for finding a minimum or a maximum value. SigOpt handles up to two optimized metrics - for more information visit multimetric optimization.Constraint
metrics are for defining success thresholds without the need to find a minimum or maximum value. SigOpt handles up to four constraints - for more information visit metric constraints. The constraint is specified as a threshold
which is a floating point number representing a threshold for success.
