Hello everyone, I would like to optimize the function "fqp" as following:
a=c(0.2,0.3,0.4) vcov=matrix(c(1,2,3,3,2,2,2,3,1),3,3) c=2 fqp <- function(b) {t(b)%*%a-0.5*c*((t(b)%*%vcov)%*%b)} with constraints like ((t(b)%*%vcov)%*%b) <= 0.5 Is there a function of doing it? Many thanks. -- View this message in context: http://www.nabble.com/Optimization%3A-non-liner-constraints-tp14841225p14841225.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
