Bug ID: 93961
Summary: Solver solution improper
Product: LibreOffice
Version: 5.1.0.0.alpha0+ Master

OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc

calc file withe the solver setup
I happened to be using Solver then updated to ver 5.0.1.2
I noticed a new option (Libre CoinMP etc).
I run a scenario and SCO solves it.
It appears Libre CoinMP prematurely returns a solution that is not correct.
I attach the file. Hopefully the solver settings all are included.
CoinMP returns 35000 (immediately, maybe from initial values?)
SCO properly returns 377396.
For whatever reason, the other Libre Linear option complains and doesn't even
proceed (also in my earlier 4.2 version I think)
The solver setup essentially is iterating integer 4 values constrained as
100<=A<=115, 200<=B<=215, 300<=C<=315, 400<=D<=415
the objective is to get (multiplication implied)
AB+AC+AD+BC+BD+CD = 377396
There are multiple solutions I believe
I am using Windows 10 64-bit, no idea what CPU.
