Hello useRs,

I'm using the command "solnp" in package "Rsolnp" to solve a general nonlinear programming problem. But I got an error that " the leading minor of order 15 is not positive definite
". Can anybody tell what may cause this error? Does it have something to do with the starting values? 

Thanks a lot!!!
