CREATION:
---------

> ./preparation.sh $tree_num  $randBase  $w1  $w2  $qos_limit  $height_limit 

this creates you ($tree_num/8) trees for lambda = 1..9  with qos and stores them in
the directory ./trees/height$height_qos$qos/

it also creates the final trees for the LP and stores them in
the directory ./trees_lp/finalTrees/height$height_qos$qos/


to create the same trees with other qos:
----------------------------------------

> ./changeQoS.sh $qosRange $fixedQoS $height

the variable $fixedQoS is 0 if you want to vary the qos-valaues between 1 and
$qosRange,
it is set to $qosRange if you want all qos-values to be $qos-Range

this stores your new trees in ./trees/height$height_qos$qosRange/
and the LP trees in ./trees_lp/finalTrees/height$height_qos$qosRange/


SIMULATION:
-----------

to run the simulation for one kind of qos:

> ./run.sh $qos $height

the results are stored in ./results/forPlots/height$height_qos$qos/
