You might be able to do a search on all values of the binary variable, if there are fewer than 20 or so. I mean, set each binary variable to 1 or 0 and solve the problem over the continuous variables. With 20 binary variables there are 2^20 ~ 10^6 possibilities, and you might be able to search that many continuous problems.
