  - getScore
```
public int getScore()
```
    The total of the broken negative constraints and fulfilled positive constraints. Their weight is included in the total. The score is usually a negative number because most use cases only have negative constraints.
    
    Returns:
    
    higher is better, usually negative, 0 if no constraints are broken/fulfilled
  - withInitScore
```
public SimpleScore withInitScore(int newInitScore)
```
    Description copied from interface: Score
    
    For example 0hard/-8soft with -7 returns -7init/0hard/-8soft.
    
    Parameters:
    
    newInitScore - always negative (except in statistical calculations), 0 if all planning variables are initialized
    
    Returns:
    
    equals score except that Score.getInitScore() is set to newInitScore
  - add
```
public SimpleScore add(SimpleScore addend)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this + addend).
    
    Parameters:
    
    addend - value to be added to this Score
    
    Returns:
    
    this + addend
  - subtract
```
public SimpleScore subtract(SimpleScore subtrahend)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this - subtrahend).
    
    Parameters:
    
    subtrahend - value to be subtracted from this Score
    
    Returns:
    
    this - subtrahend, rounded as necessary
  - multiply
```
public SimpleScore multiply(double multiplicand)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this * multiplicand). When rounding is needed, it should be floored (as defined by Math.floor(double)).
    If the implementation has a scale/precision, then the unspecified scale/precision of the double multiplicand should have no impact on the returned scale/precision.
    
    Parameters:
    
    multiplicand - value to be multiplied by this Score.
    
    Returns:
    
    this * multiplicand
  - divide
```
public SimpleScore divide(double divisor)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this / divisor). When rounding is needed, it should be floored (as defined by Math.floor(double)).
    If the implementation has a scale/precision, then the unspecified scale/precision of the double divisor should have no impact on the returned scale/precision.
    
    Parameters:
    
    divisor - value by which this Score is to be divided
    
    Returns:
    
    this / divisor
  - power
```
public SimpleScore power(double exponent)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this ^ exponent). When rounding is needed, it should be floored (as defined by Math.floor(double)).
    If the implementation has a scale/precision, then the unspecified scale/precision of the double exponent should have no impact on the returned scale/precision.
    
    Parameters:
    
    exponent - value by which this Score is to be powered
    
    Returns:
    
    this ^ exponent
  - negate
```
public SimpleScore negate()
```
    Description copied from interface: Score
    
    Returns a Score whose value is (- this).
    
    Returns:
    
    - this
  - isFeasible
```
public boolean isFeasible()
```
    Description copied from interface: Score
    
    A PlanningSolution is feasible if it has no broken hard constraints and Score.isSolutionInitialized() is true. Simple scores (SimpleScore, SimpleLongScore, SimpleBigDecimalScore) are always feasible, if their Score.getInitScore() is 0.
    
    Returns:
    
    true if the hard score is 0 or higher and the Score.getInitScore() is 0.
  - toLevelNumbers
```
public Number[] toLevelNumbers()
```
    Description copied from interface: Score
    
    Returns an array of numbers representing the Score. Each number represents 1 score level. A greater score level uses a lower array index than a lesser score level.
    When rounding is needed, each rounding should be floored (as defined by Math.floor(double)). The length of the returned array must be stable for a specific Score implementation.
    For example: -0hard/-7soft returns new int{-0, -7}
    The level numbers do not contain the Score.getInitScore(). For example: -3init/-0hard/-7soft also returns new int{-0, -7}
    
    Returns:
    
    never null

  - equals
```
public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - compareTo
```
public int compareTo(SimpleScore other)
```
  - toShortString
```
public String toShortString()
```
    Description copied from interface: Score
    
    Like Object.toString(), but trims score levels which have a zero weight. For example 0hard/-258soft returns -258soft.
    Do not use this format to persist information as text, use Object.toString() instead, so it can be parsed reliably.
    
    Returns:
    
    never null
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
  - isCompatibleArithmeticArgument
```
public boolean isCompatibleArithmeticArgument(Score otherScore)
```
    Parameters:
    
    otherScore - never null
    
    Returns:
    
    true if the otherScore is accepted as a parameter of Score.add(Score), Score.subtract(Score) and Comparable.compareTo(Object).
