Algorithm 1 The proposed SWO
Input:	$N, Nmin, \mathrm{CR}, \mathrm{TR}, t_{max}$
Output:	$\overrightarrow{{SW}^{*}}$
1.	$\mathrm{Initialize} N$ $\mathrm{female} \mathrm{wasps}, \overrightarrow{{SW}_i}$ $(i=1, 2, ..., N$), using Equation (3)
2.	$\mathrm{Evaluate} \mathrm{each} \overrightarrow{{SW}_i}$ $\mathrm{and} \mathrm{finding} \mathrm{the} \mathrm{one} \mathrm{with} \mathrm{the} \mathrm{best} \mathrm{fitness} \mathrm{in} \overrightarrow{{SW}^{*}}$
3.	t = 1; //the current function evaluation
4.	$\mathrm{while} (t < t_{max}$)
5.	$r_6$: generating a random number between 0 and 1
6.	$\mathrm{if} (r_6<\mathrm{TR}$) %% Hunting and Nesting behaviors
7.	$\mathrm{for} i=1:N$
8.	Applying Figure 2
9.	Compute $f(\overrightarrow{{SW}_i}$)
10.	t = t + 1;
11.	End for
12.	Else %% Mating Behavior
13.	$\mathrm{for} i=1:N$
14.	Applying Equation (21)
15.	t = t + 1;
16.	End for
17.	End if
18.	Applying Memory Saving
19.	Updating N using Equation (25)
20.	End while
