[Coin-discuss] OsiClp/Clp initialSolve

[John J Forrest]

Your wish is my command.

If the user has not set any hints (apart from reducing printout) and if 
there is an all slack basis OsiClp will do a ClpSimplex::initialSolve with 
some of the more exotic possibilities switched off.

[Coin-discuss] OsiClp/Clp initialSolve






Hi all,

I noticed that solving some LPs through OsiClp takes longer than solving
them with Clp (simple initialSolve), without any Hints set. From what I
can see, there is quite some code in the OsiClp initialSolve, e.g. to
see whether or not to use primal/dual simplex etc. 
Wouldn't it be a good idea for OsiClp initialSolve to rely more on Clp's
logic here, at least in no-hints/automatic mode? Or am I seeing this the
wrong way?..

Thanks,

Jan-Willem Goossens
