Abstract.   In  this  paper,  we  describe  the  algorithmic
options  of  Release  A of  {\sf  LANCELOT}, a  new  Fortran
package for  large-scale nonlinear  optimization.   We  then
present the results of intensive numerical tests and discuss
the  relative   merits  of  the  options.   The  experiments
described  involve  both  academic  and   applied  problems.
Conclusions  are finally  proposed,  both specific  to  {\sf
LANCELOT} and of more general scope.
