From January 9 to 15, 1983 the third conference on "Mathematische Optimie- rung" was held at the Mathematisches Forschungsinstitut Oberwolfach. The first
Oberwolfach meeting devoted to the subject of mathematical programming took
place in 1979. Part of its results has been documented in the Mathematical
Programming Study No. 14 entitled "Mathematical Programming at Oberwolfach".
The second Oberwolfach conference in 1981 had no proceedings volume. We feel
that mandatory proceedings announced in advance do not contribute to the spon-
taneuos workshop atmosphere of an Oberwolfach week.
After the third Oberwolfach conference we believed that many new results and
ideas presented there would justify a collection of them which eventually led to this
Mathematical Programming Study entitled "Mathematical Programming at
Oberwolfach II".
