public enum EnvironmentMode
The environment mode also allows you to detect common bugs in your implementation.
Also, aSolver
has a single Random
instance.
Some optimization algorithms use the Random
instance a lot more than others.
For example simulated annealing depends highly on random numbers,
while tabu search only depends on it to deal with score ties.
This environment mode influences the seed of that Random
instance.
Enum Constant Summary | |
---|---|
FAST_ASSERT
This mode turns on several assertions (but not all of them) to fail-fast on a bug in a Move implementation, a score rule, the rule engine itself or something else
at a reasonable performance cost (in development at least). |
|
FULL_ASSERT
This mode turns on all assertions to fail-fast on a bug in a Move implementation, a score rule, the rule engine itself or something else
at a horrible performance cost. |
|
NON_INTRUSIVE_FULL_ASSERT
This mode turns on several assertions (but not all of them) to fail-fast on a bug in a Move implementation, a score rule, the rule engine itself or something else
at a horrible performance cost. |
|
PRODUCTION
The production mode is the fastest, but not reproducible. |
|
REPRODUCIBLE
The reproducible mode is the default mode because it is recommended during development. |

public static final EnvironmentMode FULL_ASSERT
Move
implementation, a score rule, the rule engine itself or something else
at a horrible performance cost.
This mode is reproducible (see REPRODUCIBLE
mode).
This mode is intrusive because it calls the ScoreDirector.calculateScore()
more frequently
than a non assert mode.
This mode is horribly slow.
public static final EnvironmentMode NON_INTRUSIVE_FULL_ASSERT
Move
implementation, a score rule, the rule engine itself or something else
at a horrible performance cost.
This mode is reproducible (see REPRODUCIBLE
mode).
This mode is non-intrusive, unlike FULL_ASSERT
and FAST_ASSERT
.
This mode is horribly slow.
public static final EnvironmentMode FAST_ASSERT
Move
implementation, a score rule, the rule engine itself or something else
at a reasonable performance cost (in development at least).
This mode is reproducible (see REPRODUCIBLE
mode).
This mode is intrusive because it calls the ScoreDirector.calculateScore()
more frequently
than a non assert mode.
This mode is slow.
