Instead of ga, what else can I use to solve nonlinear optimization problem with integer constraints?

I'm currently working on a optimization problem which has a nonlinear objective fun, 1 linear constraint, 3 nonlinear constraints, and 10 variables that must be integers. At first I tried using ga but found that it's not effective enough because I had to run it multiple times to get better solutions.

So I'm wondering is there any other build-in functions in Matlab that can help me with this? Thanks for any help given in advance.

Here is a file exchange entry which might help, not sure how well it works.

There's also the Midaco-solver:

Sometimes: patternsearch() and round()

I didn't know that! This page seems relevant too: https://mathworks.com/matlabcentral/answers/285753-pattern-search-with-integer-decision-variable

@Sean and @Jasper thanks for the info I'll take a look to see if it works.
