i am having a BITch FIt.. i dont really feel like blogging this few days.. but i jsut wnan get this off my chest.hi peeps,
sorrie abt the meeting today.. i oversleep i got a test tml..
i too tired liao..sobosb..
anyway hear u guys have done up the net part.
it was the same as my idea.. so haiqing previous idea was kinda wrongly interpreted..
great job guys..
but after 5 hrs of playing with the program i made a few major changes.
changes 1
the fineness of net is not equal to the size of net..
do u all lrealise that ? in the modifed4 file it was coded other wise.
i remedied it liao..
fineness of net = how small the holes.
size of net = area of circle.
change 2
ask prey [if ((random-float 100) < (size * (85 + 3 * size)))[set caught caught + 1 die] ] ]
this is kinda wrong..
cos the probability of getting caught cant be represented by a generic eqn..
tink abt it
for example : size 1 : 1* (85+3) = 88
size 0.5 : o.5*(83 +1.5)=werid number
size 0.2 : 0.2* (83 + 0.6) = werid number
so i tink it is kinda wrong.. rite? hai qing u do this part one rite? u agree?maybe u can tell mi how u get the eqn?
i remedy it liao
change 3
There is a major logic error.. becos we din put one fish per patch.. there fore got a decresing trend eveyr time...
for example got 33 fishes per patch..
one patch can only give one plankton .. of cos the 32 other fishes will die of hunger..
so i remedy that too..
cahnge 4
hai qing for ur part again.. the circle part ..
u code ' let prey random-one-of fish-here '
that means the fishes tat are at the boundary will get caught..
so i tink it is wrong.. it shd be the area of the circle as the catchment area...not the boundary
do u all agree?
i remdy that as well..
cahnge 5
i have incooperated the profit concept into the program..
3 bucks for a big fish
and 2 for middel and 1 for samll fish..
hmm.. marko say that to maximise profit reduce the net size so can catch more fish...
BUT BUt...i tink
some of the small size fishes are purposely let to life so they will grow bigger and fetch more price..
we will include this pt intot he report..
cahnge 6
then how do we maximise the profit?
in fishing there is certain element of luck involved or some expericence.
therefore to maximise profit
the trawler got to move... i put in a waiting time
waiting time = time without any catch..
so the boat will move to a place wtih more fishes..
this will make our simulation robust..
i tink the porject is more of less completed.. abt 70 percent.. just need to generated the report..
before i start generating the report.. i need to finalise the program.. this shoud be the finalise one .. just need to tidy up a bit..
eveybody need to do a wirte-up on wat u have done and wat the group do..
so every one need to write nice nice thigns abt the group one.. so all will get AAAAA...
heheee
anyway got any question or problem pls highlight to mi..
if not the report will be up by this SAT night..
marko u wnana generate the report with mi?
i realise a few limitation of our programs.. i will write in thhe report.
rock mengz
how come always no one reply my mail one..
at least acknowlegde can?do u guys knoe u all need to do a wirte up each?
dont u all wanna the best for the group?
there is sometinhg wrong with the program still...
the trend is wrong... i cant start the simulation..
the draft report is hence stucked.
i tink i done a lot liao wor..
some one care to share the work?
i dont wnana meet up cos i knoe group meeting are often not productive..
so u guys need to be self motivated.
thanks
over and out
tired mingz.
with love
