<h2><span class="mw-headline" id="Prop.C3.B3sito_y_principios">Propósito y principios</span></h2>
|
|
<p>Este es un proyecto de desarrollo de software cuya intención es implementar habilidades de restricciones en el croquizador. Trata de implementar algunos elementos de la interfaz gráfica de usuario GUI y vincularlos al solucionador de restricciones.
|
|
</p><p>Los pasos de desarrollo están planificados aquí y son seguidos en el sistema de gestión de incidencias para lograr un histórico de cambios bien definido: <a rel="nofollow" class="external text" href="http://apps.sourceforge.net/mantisbt/free-cad/my_view_page.php">Sistema de gestión de incidencias</a>

|
|
<p>Para mejorar el rendimiento del solucionador del croquizador, puede realizarse un particionado basado en gráficos del sistema de restricciones. El conjunto de las restricciones y el conjunto de los parámetros desconocidos se puede presentar en un <a rel="nofollow" class="external text" href="http://es.wikipedia.org/wiki/Grafo_bipartito">grafo bipartito</a> con restricciones correspondiendo en los nodos de la izquierda y los parámetros desconocidos en los nodos de la derecha. <b>TERMINADO</b>
|
|
</p><p>Un simple pero muy utilizado paso de preprocesado reconoce cualquier subgrupo disjunto de modo que puedan ser tratado de forma separada en el solucionador. <b>TERMINADO</b>
|
|
</p><p>Por otra parte, se podría reducir el número de parámetros desconocidos que son cogidos en cuenta en la solución. Al principio de la solución debería verificar que restricciones no están ya satisfechas. Por un análisis gráfico se podría encontrar un conjunto mínimo de parámetros desconocidos que deberían tenerse en cuenta para satisfacer todas las restricciones no satisfechas.
|
|
</p><p>Dando un paso más, las subpiezas rígidas de un croquis podrían detectarse y reducirse a 3 grados de libertad (x,y,rotación).
