[Scip] how to disable some presolvers?

[Xiangyong Li]

Dear all,

I want to disable all the default presolvers. The manual says I can disable the presolver by setting "maxrounds" to 0. I do not know how to set in the program.  Use SCIPaddIntParam? 
If I do not use "SCIPincludePresolXX" at the beginning , does it mean that I disable presolver XX (I also do not implement SCIPincludeDefaultPlugins) ?    Or I should use other methods to disable the presolvers.

Thanks.

Merry Christmas!
