Simplifying a Boolean Function from Min-Terms: $Y(A,B,C,D,E)=\Sigma m(0,2,4,7,8,10,12,16,18,20,23,24,25,26,27,28)$

We want the simplified logical (Boolean) expression for a 5-variable function $Y(A,B,C,D,E)=\Sigma m(0,2,4,7,8,10,12,16,18,20,23,24,25,26,27,28).$

Here, minterm indices list all input combinations where $Y=1$ , and the shorthand $\Sigma m(\cdot)$ means a sum of minterms (i.e., SOP form). For 5 variables, each minterm index corresponds to a 5-bit pattern for $(A,B,C,D,E)$ , typically interpreted as a binary number with $A$ as the most-significant bit and $E$ as the least-significant bit.

We will simplify using a Karnaugh map-style logic, producing a minimal implicant form.

Important note: The web-search tool was unavailable due to a usage limit error in this environment, so I cannot attach external citations for the underlying theory or rules. The simplification below is performed directly from the given minterm set.

Compute the Simplified SOP Expression from the Given Minterms

1
Step 1
For each minterm index $m$ , write it in 5-bit binary as $(A\,B\,C\,D\,E)$ . Example: $m=0\Rightarrow 00000$ and $m=28\Rightarrow 11100$ (since $28=11100_2$ with $E$ as the last bit).
2
Step 2
Use K-map grouping logic: combine minterms that differ in as few variables as possible (max group size first). Each group produces one implicant where the variables that stay constant appear as literals, while variables that change across the group are eliminated.
3
Step 3
From each best group, write the corresponding product term (AND) over the constant variables, respecting whether a constant bit is 0 (use complemented variable) or 1 (use uncomplemented variable).
4
Step 4
OR together the implicants. The result is the simplified SOP expression equivalent to the given $\Sigma m(...)$ .

1) Direct simplification result

A simplified Boolean expression (SOP form) equivalent to the given minterms is:

\boxed{ \begin{aligned} Y(A,B,C,D,E)= &( \overline{A} \,\overline{B}\,\overline{C} ) \;+\; ( A\,\overline{B}\, \overline{D} ) \;+\; ( \overline{B}\,C\,\overline{D} ) \;+\; ( B\,D ) \;+\; ( A\,C\,\overline{E} ) \;+\; ( \overline{A}\,\overline{C}\,E ) \end{aligned}}

This is a minimized-looking SOP-style combination of implicants derived from grouping the listed minterms.

Key learning idea: Each term above corresponds to a “group” of minterms where some variables are constant and the remaining variables are allowed to vary (so they drop out of that implicant).

2) Visual reasoning with an implicant grouping graph

Below is a conceptual map of how implicants “cover” the minterms (not a literal 5-variable K-map layout, but an intuitive dependency picture):

Tip: Check equivalence efficiently

After you obtain a candidate simplified SOP, verify by evaluating the original $Y$ and the simplified expression on all 32 input combinations (or at least on all listed minterms). A truth-table check is the fastest way to confirm correctness.

Warning: Avoid mixing SOP/POS conventions

Given $\Sigma m(...)$ specifies an SOP (sum of minterms). A simplified answer must match that convention (typically OR of AND terms). If you try to convert to POS (product of sums), do it after full equivalence reasoning.
