<em>EmbASP</em>

<p class="lead">A framework for the integration (embedding) of Logic Programming in external systems for generic applications.
<br /> It helps developers at designing and implementing complex reasoning tasks by means of solvers on
different platforms.
</p>
<hr class="my-4">
<p>
The framework can be implemented in a object-oriented programming language of choice, easing and guiding the generation of
suitable libraries for the use of specific solvers on selected platforms. We currently provide 3
implementations (in
<a href="https://www.java.com">
<strong>Java</strong>
</a>, in
<a href="https://www.python.org">
<strong>Python</strong>
</a> and in
<a href="https://docs.microsoft.com/dotnet/csharp/language-reference/">
<strong>C#</strong>
</a>) and ready-made libraries for the embedding of the
<em>ASP (Answer Set Programming)</em> solvers
<a href="http://www.dlvsystem.com/dlv">DLV</a>,
<a href="https://www.mat.unical.it/DLV2">DLV2</a>,
<a href="https://potassco.org/clingo">clingo</a>,
<a href="http://www.kr.tuwien.ac.at/research/systems/dlvhex/">DLVHEX</a> and the
<em>PDDL (Planning Domain Definition Language)</em> cloud solver
<a href="http://solver.planning.domains">Solver.Planning.Domains</a> (SPD) on the Desktop platform and of DLV and SPD on the Mobile (Android™)
one (available only for the Java version).
</p>
<p>
However, the framework has been designed to be easily extensible and adaptable to different solvers and platforms. It is
worth to notice that solvers are invoked in different modes; for instance, SPD is invoked via a remote
connection, while for the other, binaries are effectively embedded and natively executed.

<p>
The general architecture of EmbASP is depicted in the following figure: it is intended as an abstract framework to be implemented
in some object-oriented programming language.
</p>
<p>
In addition, this architecture can be specialized for different platforms, logic languages and solvers.
</p>
<p>
The figure also reports general dependencies among the main modules.

Abstract Architecture of the framework.
<br /> Blocks overshadowed in white depict the abstract components of the framework, while
light-blue blocks represent the modules more closely related to the proposed specialization.
</figcaption>
</figure>
<p>
The framework architecture has been designed by means of four modules:
<code class="layer">Base</code>,
<code class="layer">Platforms</code>,
<code class="layer">Languages</code>, and
<code class="layer">Specialization</code>. In the following, we denote with "solver" a logic-based system that is meant to be
used by external application with the help of EmbASP.
</p>
<h4>Base Module</h4>
<p>The
<code class="layer">Base</code> module defines the basic components of the Framework.
</p>
<p>
The
<code>Handler</code> component mediates the communication between the Framework and the user that can provide
it with the input program(s) via the component
<code>InputProgram</code>, along with any desired solver's option(s) via the component
<code>OptionDescriptor</code>. A
<code>Service</code> component is meant for managing the chosen solver executions.
</p>
<p>
Two different execution modes can be made available: synchronous or asynchronous. While in the synchronous mode any call
to the execution of the solver is
<em>blocking</em> (i.e., the caller waits until the reasoning task is completed), in asynchronous
mode the call is non-blocking: a
<code>Callback</code> component notifies the caller once the reasoning task is completed. The result of the
execution (i.e., the output of the logic system) is handled by the
<code>Output</code> component, in both modes.
</p>
<h4>Platforms Module</h4>
<p>
The
<code class="layer">Platforms</code> module is meant for containing what is platform-dependent; in particular, the
<code>Handler</code> and
<code>Service</code> components from the
<code class="layer">Base</code> module that should be adapted according to the platform at hand, since they take care
of practically launching solvers.
</p>
<p>
The
<code>DesktopHandler</code> manages the
<code>DesktopService</code> for the execution of the solver on a Desktop platform, and, in a similay way, the
<code>AndroidHandler</code> manages the
<code>AndroidService</code> on an Android platform.
</p>
<h4>Languages Module</h4>
<p>
The
<code class="layer">Languages</code> module defines specific facilities for each supported logic language.
</p>
<p>
The generic
<code>Mapper</code> component is conceived as an utility for managing input and output via objects, if the
programming language at hand permits it.
</p>
<p>
The sub-module ASP comprises components such as
<code>ASPInputProgram</code> that adapts
<code>InputProgram</code> to the ASP case, while
<code>AnswerSets</code>, composed of a set of
<code>AnswerSet</code>, represents the
<code>Output</code> for ASP. Moreover the
<code>ASPMapper</code> allow the management of ASP input facts and answer sets via objects.
Similarly, the sub-module PDDL includes
<code>PDDLInputProgram</code>,
<code>Action</code>,
<code>Plan</code> and
<code>PDDLMapper</code>.
</p>
<h4>Specialization Module</h4>
<p>
The
<code class="layer">Specialization</code> module defines what is system-dependent; in particular, the
<code>Service</code>,
<code>Output</code> and
<code>OptionDescriptor</code> components from the
<code class="layer">Base</code> module should be adapted in order to effectively interact with the solver at hand.
</p>
<p>
In particular, this module contains specific extensions for the different solvers of the <code>DesktopService</code> (
<code>DLVDesktopService</code>, <code>DLV2DesktopService</code>, <code>DLVHEXDesktopService</code>,
<code>ClingoDesktopService</code> and <code>SPDDesktopService</code>) and the <code>AndroidService</code> (
<code>DLVAndroidService</code>, <code>DLV2AndroidService</code> and <code></code>). There are also the extensions of the
<code>AnswerSets</code> for ASP language (<code>DLVAnswerSets</code>, <code>DLV2AnswerSets</code>, <code>DLVHEXAnswerSets</code> and
<code>ClingoAnswerSets</code>) and of the <code>Plan</code> for PDDL language (<code>SPDPlan</code>).

<em>DLVfit</em>
</a> is a health and fitness app that monitors the user activity during the day and suggests
some workout plans that depend on her age, weight, gender and goals. The app periodically
stores some information about the user activities (running, walking, etc.) and infers
the current amount of calories burned so far. When the user asks for a workout plan,
<em>DLVfit</em> proposes a set of exercises that would allow the user to reach her daily
goal, taking into account also to her preferences. The suggested workout plans are
computed in the background by DLV via EmbASP.
</p>
<p>The ASP program used within
<em>DLVfit</em> can be found in the repository. Basically, the program guesses for possible
fitness exercises to do in order to burn the remaing calories. Each answer set represent
a possible workout plan, in which is ensured that the user's requirements about the
calories to burn and the time to spend in the workout are respected. Moreover, also
user's preferences are taken into account by means of weak constraints.</p>

<em>GuessAndCheckers</em>
</a> is a native mobile application that works as an helper for users that play "live" games
of the (Italian) checkers (i.e., by means of physical board and pieces). The app, that
runs on Android, can help a player at any time: by means of the device camera a picture
of the board is taken, and the information about the current status of the game is properly
inferred thanks to
<a href="http://opencv.org">OpenCV</a>, an open source computer vision and machine learning software; an ASP-based
artificial intelligence module then suggests the move.
</p>
<p>Thanks to EmbASP and the use of ASP,
<em>GuessAndCheckers</em> features a fully-declarative approach that made easy to develop
and improve several different strategies, also experimenting with many combinations thereof.
<br /> The source code of this application along with the Android Application Package (APK)
are available online.</p>

<em>DLVEdu</em> is an educational Android App for children, that integrates well-established
mobile technologies, such as voice or drawn text recognition, with the modeling capabilities
of ASP. In particular, it is able to guide the child throughout the learning tasks,
by proposing a series of educational games, and developing a personalized educational
path. The games are divided into four macro-areas: Logic, Numeric-Mathematical, Memory,
and Verbal Language. The usage of ASP allows the application to adapt to the game
experiences fulfilled by the user, her formative gap, and the obtained improvements.
</p>
<p>
The application continuously profiles the user by recording mistakes and successes, and dynamically builds and updates a
customized educational path along the different games. The application features a
"Parent Area", that allows parents to monitor child's achievements and to express
some preferences, such as explicit filters of some games or educational areas.

<p>Connect4 is an application that allows a user to play the popular Connect Four game (also
known as Four-in-a-Row) against an ASP-based artificial player.
<br /> The Connect Four game is played by two opponents on a vertical 7*6 rectangular board.
At each turn, the players fill the board by dropping 1 disk into one of the column so
that it falls from the top to the lowest unoccupied position in the column. The winner
is the first player who gets four of her disks in a line, connected either horizontally,
vertically, or diagonally.

Different AIs have been implemented, ranging from the most powerful one implementing advanced techniques for the perfect
play to the simplest one relying on some classical heuristic strategies. By using EmbASP,
two different versions of the same app have been built: one for Android, making use of
<a href="http://www.dlvsystem.com">DLV</a>, and one for Java-enabled desktop platforms, making use of
<a href="http://potassco.sourceforge.net">clingo</a>.
