Solving a problem in space

means investigating the attribute function of each element and the relationships among elements of
X, i.e., the structure
T, through analyzing and reasoning on domain
X. If the multi-granular computing is adopted, the same attribute function
f and structure
T will be gained by analyzing and reasoning on a certain coarse granular world [
X] of
X. Thus, [
f] and [
T] in space

must represent
f and
T to some extent, respectively. In Chapter 2, we have already discussed ...
