Folio - Examples from 'Getting Started'

Description
Different versions of a portfolio optimization problem.

Basic modelling and solving tasks:
• modeling and solving a small LP problem (foliolp)
• performing explicit initialization (folioini*)
• data input from file, index sets (foliodata, requires foliocpplp.dat)
• modeling and solving a small MIP problem with binary variables (foliomip1)
• modeling and solving a small MIP problem with semi-continuous variables (foliomip2)
• modeling and solving QP and MIQP problems (folioqp, requires foliocppqp.dat)
• modeling and solving QCQP problems (folioqc, requires foliocppqp.dat)
• heuristic solution of a MIP problem (folioheur)
• enlarged version of the basic MIP model (foliomip3 with include file readfoliodata.c_, to be used with data set folio10.cdat)
• defining an integer solution callback (foliocb)
• using the MIP solution pool (foliosolpool)
• using the solution enumerator (folioenumsol)
• handling infeasibility through deviation variables (folioinfeas)
• retrieving IIS (folioiis)
• using the built-in infeasibility repair functionality (foliorep)
