Basic Examples (2) 

Select subsets from {1,2,3,4,5} that add up to 10:

In[1]:=

Out[1]=

Select subsets of length 2 to 4 that sum up to a prime:

In[2]:=

Out[2]=

Scope (4) 

Select all subsets of length 2 that add up to 6:

In[3]:=

Out[3]=

Select all subsets that add up to 0:

In[4]:=

Out[4]=

Select all subsets of odd length that add up to a prime:

In[5]:=

Out[5]=

Select the first eight subsets that add up to a prime:

In[6]:=

Out[6]=

Applications (1) 

Find subsets that add up to 25:

In[7]:=

Out[7]=

Properties and Relations (2) 

The main difference between Select and Subsets, and SelectSubsets is the amount of memory used:

In[8]:=

Out[8]=

Compared to naive implementation, which requires roughly a 1000 times more memory:

In[9]:=

Out[9]=

Verify the result is the same:

In[10]:=

Out[10]=

With a criterion that is a tautology, SelectSubsets and Subsets give the same results:

In[11]:=

Out[11]=

Possible Issues (1) 

SelectSubsets might not be able to return the number of elements that are requested:

In[12]:=

Out[12]=

Neat Examples (2) 

Find subsets that add up to 0:

In[13]:=

Out[14]=

Visualize the lengths of the lists:
