Is there a version of SearchPhases.java written in C#?  There are C# interfaces like IIntVarEval but it's unclear how to use them.

Hello Donovan,
You can find an example of how using SearchPhases here: CPLEX_Studio201/cpoptimizer/examples/src/csharp/Sports.cs.
Several predefined evaluators exist in CP Optimizer, i.e: Simple variable selection or i.e.: Simple value selection, but at this time, custom evaluators are not available in the C# API of CP Optimizer (see CP Optimizer User's Manual).
I hope this helps.

I have used the basic ones for a long time now but came across this in the reference manual which I tried to make work.  "It is possible also to define your own evaluator, which makes it possible to define an evaluation of the assignment of an integer variable to a value."  How is this last statement true then?
Thanks

This is an error into the documentation.
As mentioned above, at this time, custom evaluators are not available in the C# API of CP Optimizer.
They are available in C++ and Java API.

CP Optimizer .NET Languages API

IIntValueEval Interface

Members See Also

An evaluator of integer values is an object that is used by value selectors (IValueSelector) to define instantiation strategies.

Namespace: ILOG.CP
Assembly: ILOG.CP (in ILOG.CP.dll)

Syntax

C#
public interface IIntValueEval

Visual Basic
Public Interface IIntValueEval

Remarks

There are many predefined evaluators of integer values available via the CP class. It is possible also to define your own evaluator, which makes it possible to define an evaluation of the assignment of an integer variable to a value.
