Fig. 5.3 Exploration links within and between design subspaces (van Langen and Brazier
Contemporary AI researchers take a somewhat different approach. In their view
the boundary of the design space, which integrates problem and solution spaces, are
flexible a priori and define the realm of undiscovered designs, or possible solutions.
Because of the complexity of design problems some researchers suggest separate,
yet interconnected, subspaces in which different design knowledge is reasoned
concerning design process objectives, design object descriptions, and sets of design
links among objects in different subspaces. The links represent acts of exploration.
relationship between discovered and undiscovered designs, where 'design' is an
instance of design, or a designed entity. Within the flexible boundaries of the
undiscovered design space we find enclosed discovered subspaces of known design
instances. This is shown in Fig.

. The links, or paths, between instances of
discovered and undiscovered designs are called tendrils and they stand for design
exploration. The shorter the tendril, the less effort is required to arrive at the
undiscovered design instance. Undiscovered designs that have paths, or connectiv-
ity, to a large number of discovered designs—are advantageous.
