Manipulating derivation forests by scheduling techniques
1986
Theoretical Computer Science
Preserved Fulltext
We develop various kinds of pumping, obtaining bounds on the sizes of k-derivations and k-derivation forests. ...
We solve the various membership problems left open in (Gonczarowski/Warmuth, 1985) , for arbitrary grammars, using Scheduling Theory. ...
Manipulating derivation forests by scheduling techniques 93 We now proceed to define schedules on forests. ...

We contrast the traditional timber management plan with today's sustainable forest management plan, realizing the basis of both plans is by definition the forest or the timber. ...
One cannot ignore the fact that all forest management plans accomplish silvicultural objectives via manipulation of timber density variables, like stocking and spacing. ...
Wildlife values, recreation values, water values, aesthetic values, all are manipulated by manipulating the timber resources. ...

Here, using the scheduling theory approach as introd ed by Gonczarowski and Warmuth (1985), we prove a pumping property of 2-context-free languages. ...
Languages that are generated by context-free grammars in k-parallel derivations (i.e., at each step exactly k nonterminals, k 2 1, are rewritten) are called k-context-free languages. ...
In proving the pumping property we rely extensively on scheduling theory arguments. The use of scheduling techniques for manipulating derivation forests was introduced in [d, 71. ...
