Create a list of empty lists
can't really figure out where to make it return no, i tried all possible ways of adding fail or !. here is the final code binpack(_,_,[],AnswerListOfLists):- !. %if no input is provided exit %Predicate binpack/4 which operates in mode (+,+,+,-)... -
Create a list of empty lists
ok done it, it works perfect. but i need one more last advice here is the code: binpack(_,_,[],AnswerListOfLists):- !. binpack(NumBins,Capacity,ObjectList,AnswerListOfLists):- createBins([[]],NumBins,Bins), (addIn(ObjectList,Capacity,Bins,AnswerListOfLists); perm(ObjectLisT,RandomList)... -
Create a list of empty lists
thank you joel very much, you've been really helpful thanks. This works fine,but i still need to figure out one thing: when a number comes that doesn't fit in any bin the program fails, if that happens i need it go back, re-arrange the object list and start again from the start. here is what... -
Create a list of empty lists
your answer confused me a little bit, so one change is to make C=< Cap do nothing when it fails? or just leave it as it is? and the second change is to do something when all numbers are used? this is what i tried to do but now 2 things happen, when it reaches the last bin and the next number... -
Create a list of empty lists
ok fixed that but now a different problem here is the code: binpack(NumBins,Capacity,ObjectList,AnswerListOfLists):- createBins([[]],NumBins,Bins), addIn(ObjectList,Capacity,Bins,AnswerListOfLists). createBins(L1,N,L2):-createBins(L1,N,L2,N). createBins([],_,[],_). createBins([_|Xs],N,Ys,0)... -
Create a list of empty lists
ok found how to do that but now i have an other problem here is my code: binpack(NumBins,Capacity,ObjectList,AnswerListOfLists):- createBins([[]],NumBins,Bins), addIn(ObjectList,Capacity,Bins,AnswerListOfLists). createBins(L1,N,L2):-createBins(L1,N,L2,N). createBins([],_,[],_)... -
Create a list of empty lists
Hello i need to create a list of empty lists eg [ [], [] , [] , []] but the problem is, i need the exact number of empty lists provided from the input.. for example if i give createEptyLists(4,X). it should return X= [ [], [] , [] , [] ]. how can i implement this " for i=<InputNumberOfLists" ? -
Prolog Read a function from a file
fixed it, this works: num(zero,0). num(one,1). num(two,2). num(three,3). num(four,4). num(five,5). num(six,6). num(seven,7). num(eight,8). num(nine,9). num(ten,10). plus(X,Y,Z):- num(X,NX), num(Y,NY), Z is NX + NY. minus(X,Y,Z):- num(X,NX)... -
Prolog Read a function from a file
ok , sorry about this, i got another problem. I am supposed to read several lines from the text, for example the txt file looks like: three plus zero. two times four. stop. two minus one. so I need to make the program read all the lines until it finds a stop, and print the results in a new... -
Prolog Read a function from a file
fixed it, i was reading the number zero and i hadn't instantiated it. Thanks joel you were really helpfull ;) -
Prolog Read a function from a file
thanks for the reply, sadly i need this to work in gprolog and use read_atom (which is not supported in swi-prolog) to read from a txt file. so with your help i changed the code to this: num(one,1). num(two,2). num(three,3). num(four,4). num(five,5). num(six,6). num(seven,7). num(eight,8)... -
Prolog Read a function from a file
Hi, I need to build this program to read from a file sentences like "three plus zero." (all of them 3 words and just a simple operation) and return the result of the arithmetic operation. The solution I thought of was to use read_atom to store each word in X,Y,Z atoms. then make a list of them...
