r17635 branched trunk

[chaider]

r17638 Added first part of feynman equations as instances

[chaider]

r17639

• Added rest of part I equations
• Set Training/Test Partitions to 10⁵

[chaider]

r17640 Added equations of part II

[chaider]

r17641 Added part III of feynman equations

[chaider]

r17642 Added field and constructor to define sample size in instances

[chaider]

r17643 Added feynman bonus equations

[chaider]

r17644 fixed exponent in Feynman II.6.15a

[chaider]

r17645

• Updated instances (removed 2*pi term from equations)
• Added instances to InstanceProvider

[chaider]

r17647

• Added possibility to add noise to the feynman instances
• Sorted instances by name

[chaider]

r17649 Added noise instances for feynman bonus instances

[chaider]

r17659 Fixed issues in some instances

[gkronber]

• r17670 Fix order of instances and add information on reference publication and description.
• r17671 Removed "Feynman" prefix from all instances
• r17672 rename file for reodering
• r17673 reorder instances
• r17674 small changes while reviewing
• r17675 reordering part1
• r17676 reorder part2
• r17677 update class names to match file names, split problem instances into 'small' and 'large' instances with separate providers
• r17678 changed title for noise part

[gkronber]

• r17681: merged r17646:17648 from trunk to branch to prepare for reintegration
• r17682: merged r17638:17681 from branch into trunk

[gkronber]

r17683: deleted branch

[gkronber]

r17684: include correct files in .csproj

The problem instances provider should not be the default selected one. Instead CSV should be the default. Right now AI is ordered first.

[gkronber]

Discovered problem instance providers are ordered by Name in ProblemView line 70:

            problemInstanceProviderComboBox.DataSource = ProblemInstanceProviders.OrderBy(x => x.Name).ToList();

[gkronber]

r17804: start Name of CVS instance provider with a space to make sure it is ordered first.

[gkronber]

r17805:

• Use the same noise levels and calculation as in our experiments for the IEEE TeC paper.
• Reorder instances by name first and noise level second.
• Remove number of samples from the name.
