1. marked sets or target domains
    1. target domains
      1. = known domain + unknown domain
    2. the examples in marked sets:
      1. 0 marked: 0,00,000,0000,........
      2. 01 marked: ε,01,001,0001,........
      3. ... marked: .....................................
      4. 10 marked: ε,10,100,1000,........
      5. 1 marked: 1,11,111,1111,........
  2. single set or complete sub-domain
    1. examples of elements in single set or in complete sub-domain: e.g.1. 0,1 e.g.2. Excited, Inhibition e.g.3. on,off
  3. hierarchical sets or super-sub-domains
    1. examples of elements and combination of elements in hierarchical sets or in super-sub-domains:e.g.1. 0,1 00,01,10,11 000,001,010,011,110,101,100,111 ............................................................................................ ......................................................................................................................
