 All these hypotheses can be examined with respect to different complexity metrics. All these hypotheses can be examined with respect to different complexity metrics.
  
-Hypothesis 1 can be regarded ​true by definition. If the solution cannot be implemented ​fast, it is not simple. ​+Hypothesis 1 is true by definition. If the solution cannot be implemented ​quickly, it is not simple. ​
  
 Though hypotheses 2 and 3 are not true by definition but they can be regarded intuitively clear. Nevertheless there is some research. In ((Virginia R. Gibson and James A. Senn: //​[[http://​dl.acm.org/​citation.cfm?​id=62073|System Structure and Software Maintenance Performance]]//​)) a system was improved in two steps resulting in three variants of the same system. Several metrics show that the improvements reduced complexity. 36 programmers with varying experience conducted three different maintenance tasks and their performance was measured. The results indicate that the improvements also improved maintainability. Several other studies support the correlation between complexity and maintainability((Chris F. Kemerer: //​[[http://​link.springer.com/​article/​10.1007%2FBF02249043?​LI=true|Software complexity and software maintenance:​ A survey of empirical research]]//​)). Though hypotheses 2 and 3 are not true by definition but they can be regarded intuitively clear.
