1. Herding instincts and tractability can be assessed in noncompetitive herding tests. 2. A sufficient condition for tractability is related to expressibility in Datalog. 3. As explained above, tractability requires that two conditions are met. 4. A particular aspect of malleability is the tractability of identity. 5. Tractability can be obtained by considering specific classes of constraint satisfaction problems.6. For reasons of tractability , it is often assumed in continuously divisible. 7. These systems are used because of their genetic tractability and their fast growth. 8. Owing to its tractability , models have often incorporated the power-law function 9. A frequency shift does not undermine the mathematical tractability of the complex signal representation. 10. Mainstream economics uses infinitesimal values in much of its analysis for reasons of mathematical tractability .
