a list containing: scores, cooling, startTemp, temperature,
temperature.step, nIterations and optimality.
Details can be found below.
scores: A- or D- optimality score of all accepted designs during optimization
process.
cooling: describes the cooling step in the Simulated Annealing, defined as (new.score $-$ now.score)/ now.score.
startTemp:starting temperature of the simulated annealing process.
temperature:final temperature that the simulated annealing reaches.
temperatureStep:temperature decreasing step in the simulated annealing (SA) process.
nIterations:number of iterations in the simulated annealing method.
optimality:type of optimality, i.e. "A" (A-optimality) or "D"
(D-optimality). A-optimality minimizes $Trace((X'X)^-1)$,
which corresponds to minimum average variance of the
parameter estimates. D-optimality minimizes $det(X'X)^-1$,
which corresponds to minimum generalized variance of the
parameter estimates.
