## Abstract A method is presented whereby the refractiveβindex profile (RIP) can be reconstructed from sets of effective indexes measured with different mode types and external refractive indexes. Singleβmode waveguide RIP characterization can be easily realized using an indexβmatching liquid at a

β¦ Synopsis
I n this pa.per the problem of uniehge selection with inequality constraint9 is formulated. If the predictor and criterion variables are all normally dietributed, this problem can be written a8 a convex programming problem, with a linear objective function and with linetlr constraint8 and a quedratio constraint. Ueing the duality theory, for convex nonlinear programming it ie proved. that its dual problem can be tranaformed into a convex minimization problem with non-negativity conditions. Good computational methods are known for solving thie problem. By the help of the dual problem sufficient conditions for a aolution of the original primal problem are derived and illustrated by an example of practical interest.
