Excluding derived variables from inertia.
In the example encoding, derived variables were accidentally included in
the inertia rule, as this only checked the position of the parameter.
This commit fixes this by only allowing common variables (and not
derived ones) within the inertia rule.

Minor formatting.
This change doesn’t affect derived variables, because these aren’t
affected by the “caused” predicate (the “caused” predicate requires a
variable to be in the postcondition of an action, and these may never be
derived variables).

Fixed handling of goal in example encoding.
The example encoding assumed that derived predicates weren’t necessary
in the final time step. This is, however, incorrect, as the goal may
have a precondition that requires derived predicates. In this case, the
derived variables must be evaluated for the final time step.

Moved outdated encodings to separate directory.
These encodings need to be updated to match the new output format. Until
this is done, hide these files in a separate directory in order not to
confuse users.

Updated cxxopts to 2.0.0.
Starting from version 2.0.0, cxxopts returns a ParseResult object
instead of storing the results directly within the Options structure.
Additionally, Booleans are handled slightly differently.

These two changes required some minor adjustment of the command-line
argument parsing code.

Updated readme for release 3.1.0.
This adds a section about the new commands, updates out-of-date
references, and highlights the translator as the currently most
interesting component.

Added tests for derived predicate numbering.
These tests ensure that derived predicates are numbered correctly,
whether they are introduced by the domain, the problem, or both.

Added normalization tests for nested expressions.
These tests ensure that nested expressions in preconditions and effects
are correctly flattened via derived predicates.

Added normalization tests for negations.
These tests ensure that multiple negations are eliminated, negated
quantifiers are replaced appropriately, negations introduced by
reduction are correctly handled, and negated disjunctions and
conjunctions are replaced according to De Morgan’s rules.
2017-11-15 18:53:43 +01:00
9e9040cac0
Added normalization tests for “forall” statements.
These tests ensure that universal quantifiers are correctly reduced to
negated existential quantifiers over the negated argument via derived
predicates in preconditions (nested and not) and goal descriptions.
2017-11-15 17:26:56 +01:00

Added normalization tests for implications.
These tests ensure that implications are correctly reduced to
disjunctions in preconditions (nested and not) and goal descriptions.

Added basic normalization tests.
These tests make sure that simple PDDL descriptions are preserved by
normalization.

Removed obsolete test file.
This file will soon be replaced by a dedicated test suite in the pddl
library and is obsolete thus.

Requiring goal to contain only one statement.
Previously, the parser read the first statement of the goal as its
precondition, but didn’t check that it was properly terminated with a
closing parenthesis. This allowed arbitrary text to be included within
the goal description without error, which was incorrect.

This commit fixes this issue and adds a corresponding unit test.

Made form of variables within values consistent.
Previously, variables referenced within values were unpacked within
values. This was inconsistent, because all predicates are usually used
in their unpacked form in the rest of the output format. This commit
makes this consistent by using variables in their packed form within
values, making it more compact to handle them.

Fixed syntax error at end of initial state facts.
Due to a mistake in commit 6d07fcb, the closing parenthesis and period
at the end of initial state facts was omitted. This adds these back in
order to solve this syntax error.

Boost packages from the Travis configuration.

Removed Boost dependency in assertions.
Instead of using BOOST_ASSERT, this commit changes all assertions to
plain C-style assertions in order to drop the dependency to Boost.

Removed Boost dependency in unit tests.
Some of the unit tests depended on Boost’s null_sink to redirect the
unwanted test output to /dev/null. This commit adds a simple
NullOutputStream as a replacement and removes the obsolete Boost
includes.

Removed Boost dependency in language distinction.
As Boost isn’t used in the rest of this project anymore, this commit
removes the unnecessary dependency to boost::bimap just for language
detection, and replaces it with a simple std::map instead.

Ensuring that goal is variable-free.
Even though the parser shouldn’t be able to put variables into the goal
description, the AST theoretically allows for this case. This commit
adds a defensive check that goal descriptions are variable-free.

Added support for derived predicates in goals.
By accident, the support for derived predicates in goals was missing.
This commit adds this, in a very similar way to how normal predicates
are handled in the goal description.

Error for derived predicates in initial state.
Previously, derived predicates in the initial state weren’t handled at
all. That’s not an issue, because derived predicates shouldn’t occur in
the initial state. However, as a defensive measure, this commit adds an
error thrown in such cases.

Translating derived predicates of problems.
While derived predicates stemming from the domain were already
translated, the ones from the problem were missing. This commit fixes
that, although it duplicates the definition of “contains.”

Fixed incorrect derived predicate IDs in problems.
The IDs of derived predicates within problems were accidentally starting
with 1 again, colliding with the IDs of derived predicates in the
domain. With this fix, the IDs are continuously incremented, even after
switching from domain to problem.
