WORST_CASE(?,O(n^1))
* Step 1: NaturalPI WORST_CASE(?,O(n^1))
    + Considered Problem:
        - Strict TRS:
            a__c() -> c()
            a__c() -> d()
            a__g(X) -> a__h(X)
            a__g(X) -> g(X)
            a__h(X) -> h(X)
            a__h(d()) -> a__g(c())
            mark(c()) -> a__c()
            mark(d()) -> d()
            mark(g(X)) -> a__g(X)
            mark(h(X)) -> a__h(X)
        - Signature:
            {a__c/0,a__g/1,a__h/1,mark/1} / {c/0,d/0,g/1,h/1}
        - Obligation:
            innermost runtime complexity wrt. defined symbols {a__c,a__g,a__h,mark} and constructors {c,d,g,h}
    + Applied Processor:
        NaturalPI {shape = StronglyLinear, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
    + Details:
        We apply a polynomial interpretation of kind constructor-based(stronglyLinear):
        The following argument positions are considered usable:
          none
        
        Following symbols are considered usable:
          {a__c,a__g,a__h,mark}
        TcT has computed the following interpretation:
          p(a__c) = 11    
          p(a__g) = 9 + x1
          p(a__h) = 4 + x1
             p(c) = 4     
             p(d) = 10    
             p(g) = 3 + x1
             p(h) = 1 + x1
          p(mark) = 9 + x1
        
        Following rules are strictly oriented:
            a__c() = 11       
                   > 4        
                   = c()      
        
            a__c() = 11       
                   > 10       
                   = d()      
        
           a__g(X) = 9 + X    
                   > 4 + X    
                   = a__h(X)  
        
           a__g(X) = 9 + X    
                   > 3 + X    
                   = g(X)     
        
           a__h(X) = 4 + X    
                   > 1 + X    
                   = h(X)     
        
         a__h(d()) = 14       
                   > 13       
                   = a__g(c())
        
         mark(c()) = 13       
                   > 11       
                   = a__c()   
        
         mark(d()) = 19       
                   > 10       
                   = d()      
        
        mark(g(X)) = 12 + X   
                   > 9 + X    
                   = a__g(X)  
        
        mark(h(X)) = 10 + X   
                   > 4 + X    
                   = a__h(X)  
        
        
        Following rules are (at-least) weakly oriented:
