Method Summary

Modifier and Type	Method	Description
`boolean`	`evaluate()`	Tries to evaluate the kappa term, if the evaluation is successful then the next call of value returns the evaluated value.
`Set<KappaTerm>`	`getSubTerms()`	Processes all the sub-terms
`int`	`greaterEqualThan()`
`String`	`toString()`
`int`	`value()`	The neutral element is zero, that means if the sum contains no elements this method returns zero

  - greaterEqualThan
```
public int greaterEqualThan()
```
    Specified by:
    
    greaterEqualThan in interface KappaTerm
    
    Returns:
    
    The minimum value of this kappa term, such that the caller knows the kappa term is greater or equal the returned value.
